​Chapter 10 Anapana Samyutta (On Breathing)

SN 54.1 Ekadhamma Sutta: One Thing

At Savatthi. There the Blessed One said this: "Bhikkhus, one thing, when developed and cultivated, is of great fruit and benefit. What one thing? Mindfulness of breathing. And how, bhikkhus, is mindfulness of breathing developed and cultivated so that it is of great fruit and benefit? "

"Here, bhikkhus, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes out."

"Breathing in long, he knows: 'I breathe in long'; or breathing out long, he knows: 'I breathe out long.' Breathing in short, he knows: 'I breathe in short'; or breathing out short, he knows: 'I breathe out short: He trains thus: 'Experiencing the whole body, I will breathe in'; he trains thus: 'Experiencing the whole body, I will breathe out.' He trains thus: 'Tranquilizing the bodily formation, I will breathe in'; he trains thus: 'Tranquilizing the bodily formation, I will breathe out.'"

"He trains thus: 'Experiencing rapture, I will breathe in'; he trains thus: 'Experiencing rapture, I will breathe out.' He trains thus: 'Experiencing happiness, I will breathe in'; he trains thus: 'Experiencing happiness, I will breathe out.' He trains thus: 'Experiencing the mental formation, I will breathe in'; he trains thus: 'Experiencing the mental formation, I will breathe out.' He ​trains thus: 'Tranquilizing the mental formation, I will breath in'; he trains thus: 'Tranquilizing the mental formation, I will breathe out.'"

"He trains thus: 'Experiencing the mind, I will breathe in'· h trains thus: 'Experiencing the mind, I will breathe out.' He trains thus: 'Gladdening the mind, I will breathe in'; he trains thus: 'Gladdening the mind, I will breathe out: He trains thus; 'Concentrating the mind, I will breathe in'; he trains thus: 'Concentrating the mind, I will breathe out: He trains thus: 'Liberating the mind, I will breathe in'; he trains thus: 'Liberating the mind, I will breathe out.'"

"He trains thus: 'Contemplating impermanence, I will breathe in'; he trains thus: 'Contemplating impermanence, I will breathe out.' He trains thus: 'Contemplating fading away, I will breathe in'; he trains thus: 'Contemplating fading away, I will breathe out.' He trains thus: 'Contemplating cessation, I will breathe in'; he trains thus: 'Contemplating cessation, I will breathe out: He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out.'"

"It is, bhikkhus, when mindfulness of breathing is developed and cultivated in this way that it is of great fruit and benefit."

(Breath meditation is very beneficial. It is developed by going into seclusion, establishing mindfulness on the breath, and proceeding through sixteen stages.)

SN 54.2 Bojjhaṅga Sutta: Factors of Enlightenment

"Bhikkhus, mindfulness of breathing, when developed and cultivated, is of great fruit and benefit. And how, bhikkhus, is mindfulness of breathing developed and cultivated so that it is of great fruit and benefit? "

"Here, bhikkhus, a bhikkhu develops the enlightenment factor of mindfulness accompanied by mindfulness of breathing, based upon seclusion, dispassion, and cessation, maturing in release. He develops the enlightenment factor of discrimination of states ...... the enlightenment factor of equanimity accompanied by mindfulness of breathing, based upon seclusion, dispassion, and cessation, maturing in release. "

"It is in this way, bhikkhus, that mindfulness of breathing is developed and cultivated so that it is of great fruit and benefit." 

(Breath meditation is very beneficial. It is developed together with the seven factors of awakening.)
​
SN 54.3 Suddhika Sutta: Simple Version

"Bhikkhus, mindfulness of breathing, when developed and cultivated, is of great fruit and benefit. And how, bhikkhus, is mindfulness of breathing developed and cultivated so that it is of great fruit and benefit?"

"Here, bhikkhus, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes out . . . . (all as in §1) ... He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out.' "

"It is in this way, bhikkhus, that mindfulness of breathing is developed and cultivated so that it is of great fruit and benefit."

(Breath meditation is very beneficial. It is developed by going into seclusion, establishing mindfulness on the breath, and proceeding through sixteen stages.)

SN 54.4 Paṭhamaphala Sutta: Fruits (1)

(All as in preceding sutta, with the following addition)

"When, bhikkhus, mindfulness of breathing has been developed and cultivated in this way, one of two fruits may be expected: either final knowledge in this very life or, if there is a residue of clinging, the state of non-retuming."

 (Breath meditation is very beneficial. When developed it leads to perfection or once-return.)

SN 54.5 Dutiyaphala Sutta: Fruits (2)

(All as in §3, with the following addition)

"When, bhikkhus, mindfulness of breathing has been developed and cultivated in this way, seven fruits and benefits may be expected. What are the seven fruits and benefits? "

"One attains final knowledge early in this very life. If one does not attain final knowledge early in this very life, then one attains final knowledge at the time of death. If one does not attain final knowledge early in this very life or at the time of death, then with the utter destruction of the five lower fetters one becomes an attainer of Nibbana in the interval. "

"If one does not attain final knowledge early in this very life ... or become an attainer of Nibbana in the interval, then with the utter destruction of the five lower fetters one becomes an attainer of Nibbana upon landing. If one does not attain final knowledge early in this very life . . or become an attainer of Nibbana upon landing, then with the utter destruction of the five lower fetters one becomes an attainer of Nibbana without exertion."

"If one does not attain final knowledge early in this very life . .. or become an attainer of Nibbana without exertion, then with the utter destruction of the five lower fetters one becomes an attainer of Nibbana with exertion. If one does not attain final knowledge early in this very life ... or become an attainer of Nibbana with exertion, then with the utter destruction of the five lower fetters one becomes one bound upstream, heading towards the Akanittha realm. "

"When, bhikkhus, mindfulness of breathing has been developed and cultivated in this way, these seven fruits and benefits may be expected."

(Breath meditation is very beneficial. When developed it leads to perfection or one of the lesser attainments.)

SN 54.6 Ariṭṭha Sutta: Arittha

At Savatthi. There the Blessed One said this: "Bhikkhus, do you develop mindfulness of breathing?"

When this was said, the Venerable Arittha said to the Blessed One: "Venerable sir, I develop mindfulness of breathing."
"But in what way, Arittha, do you develop mindfulness of breathing?"
"I have abandoned sensual desire for past sensual pleasures, venerable sir, I have gotten rid of sensual desire for future sensual pleasures, and I have thoroughly dispelled perceptions of aversion towards things internally and externally. Just mindful I breathe in, mindful I breathe out. It is in this way, venerable sir, that I develop mindfulness of breathing."

"That is mindfulness of breathing, Arittha, I do not say that it is not. But as to how mindfulness of breathing is fulfilled in detail, Arittha, listen and attend closely, I will speak."
"Yes, venerable sir," the Venerable Arittha replied.

The Blessed One said this: "And how, Arittha, is mindfulness of breathing fulfilled in detail? Here, Arittha, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes ​out ... . He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out. "

"It is in this way, Arittha, that mindfulness of breathing is fulfilled in detail."

(When the Buddha asks Venerable Ariṭṭha about breath meditation, his answer, while not incorrect, does not do full justice to the practice.)

SN 54.7 Mahākappina Sutta: Mahakappina

At Savatthi. Now on that occasion the Venerable Mahakappina was sitting not far from the Blessed One, with his legs folded crosswise, holding his body straight, having set up mindfulness in front of him. The Blessed One saw him sitting nearby, with his legs folded crosswise, his body straight, having set up mindfulness in front of him. Having seen him, he addressed the bhikkhus thus: "Bhikkhus, do you see any shaking or trembling in this bhikkhu's body?"

"Venerable sir, whenever we see that venerable one, whether he is sitting in the midst of the Sangha or sitting alone in private,we never see any shaking or trembling in that venerable one's body."
"Bhikkhus, that bhikkhu gains at will, without trouble or difficulty, that concentration through the development and cultivation of which no shaking or trembling occurs in the body, and no shaking or trembling occurs in the mind. And what concentration is it through the development and cultivation of which no shaking or trembling occurs in the body, and no shaking or trembling occurs in the mind? "

"It is, bhikkhus, when concentration by mindfulness of breathing has been developed and cultivated that no shaking or trembling occurs in the body, and no shaking or trembling occurs in the mind. And how, bhikkhus, is concentration by mindfulness of breathing developed and cultivated so that no shaking or trembling occurs in the body, and no shaking or trembling occurs in the mind? "

"Here, bhikkhus, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes out. ... He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out: "

"It is, bhikkhus, when concentration by mindfulness of breathing has been developed and cultivated in this way that no shaking or trembling occurs in the body, and no shaking or trembling occurs in the mind."

(The Buddha sees Venerable Mahākappina meditating nearby and points out that his steadiness and tranquility are due to practicing breath meditation.)

SN 54.8 Padīpopama Sutta: The Simile of the Lamp

"Bhikkhus, concentration by mindfulness of breathing, When developed and cultivated, is of great fruit and benefit. And how bhikkhus, is concentration by mindfulness of breathing developed and cultivated so that it is of great fruit and benefit? "

"Here, bhikkhus, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes out .... He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out."

"It is in this way, bhikkhus, that concentration by mindfulness of breathing is developed and cultivated so that it is of great fruit and benefit."

"I too, bhikkhus, before -my enlightenment, while I was still a bodhisatta, not yet fully enlightened, generally dwelt in this dwelling. While I generally dwelt in this dwelling, neither my body nor my eyes became fatigued and my mind, by not clinging, was liberated from the taints. "

"Therefore, bhikkhus, if a bhikkhu wishes: 'May neither my body nor my eyes become fatigued and may my mind, by not clinging, be liberated from the taints: this same concentration by mindfulness of breathing should be closely attended to."

"Therefore, bhikkhus, if a bhikkhu wishes: 'May the memories and intentions connected with the household life be abandoned by me,' this same concentration by mindfulness of breathing should be closely attended to. Therefore, bhikkhus, if a bhikkhu wishes: 'May I dwell perceiving the repulsive in the unrepulsive,' this same concentration by mindfulness of breathing should be closely attended to. If a bhikkhu wishes: 'May I dwell perceiving the unrepulsive in the ​repulsive,' this same concentration by mindfulness of breathing should be closely attended to. If a bhikkhu wishes: 'May I dwell perceiving the repulsive in the unrepulsive and the repulsive,' this same concentration by mindfulness of breathing should be closely attended to. If a bhikkhu wishes:'May I dwell perceiving the unrepulsive in the repulsive and the unrepulsive,' this same concentration by mindfulness of breathing should be closely attended to."

"If a bhikkhu wishes: 'Avoiding both the unrepulsive and the repulsive, may I dwell equanimous, mindful and clearly comprehending,' this same concentration by mindfulness of breathing should be closely attended to. Therefore, bhikkhus, if a bhikkhu wishes: 'May I, secluded from sensual pleasures, secluded from unwholesome states, enter and dwell in the first jhana, which is accompanied by thought and examination, with rapture and happiness born of seclusion,' this same concentration by mindfulness of breathing should be closely attended to."

"Therefore, bhikkhus, if a bhikkhu wishes: 'May I, with the subsiding of thought and examination, enter and dwell in the second jhana, which has internal confidence and unification of mind, is without thought and examination, and has rapture and happiness born of concentration,' this same concentration by mindfulness of breathing should be closely attended to. "

"Therefore, bhikkhus, if a bhikkhu wishes: 'May I, with the fading away as well of rapture, dwell equanimous and, mindful and clearly comprehending, may I experience happiness with the body; may I enter and dwell in the third jhana of which the noble ones declare: "He is equanimous, mindful, one who dwells happily,''' this same concentration by mindfulness of breathing should be closely attended to. "

"Therefore, bhikkhus, if a bhikkhu wishes: 'May I, with the abandoning of pleasure and pain, and with the previous passing away of joy and displeasure, enter and dwell in the fourth jhana, which is neither painful nor pleasant and includes the purification of mindfulness by equanimity,' this same concentration by mindfulness of breathing should be closely attended to. "

"Therefore, bhikkhus, if a bhikkhu wishes: 'May I, with the complete transcendence of perceptions of forms, with the passing away of perceptions of sensory impingement, with non-attention to perceptions of diversity, aware that "space is infinite," enter and dwell in the base of the infinity of space,' this same concentration by mindfulness of breathing should be closely attended to. "

"Therefore, bhikkhus, if a bhikkhu wishes: 'May I, by completely transcending the base of the infinity of space,  aware that "consciousness is infinite," enter and dwell in the base of the infinity of consciousness,' this same concentration by mindfulness of breathing should be closely attended to. Therefore, bhikkhus, if a bhikkhu wishes: 'May I, by Completely transcending the base of the infinity of consciousness aware that "there is nothing," enter and dwell in the base of nothingness,' this same concentration by mindfulness of breathing should be closely attended to. "

"Therefore, bhikkhus, if a bhikkhu wishes: 'May I, by completely transcending the base of nothingness, enter and dwell in the base of neither:perception-nor-non-perception,' this same concentration by mindfulness of breathing should be closely attended to. Therefore, bhikkhus, if a bhikkhu wishes: 'May I, by completely transcending the base of neither-perception-nor-non-perception, enter and dwell in the cessation of perception and feeling,' this same concentration by mindfulness of breathing should be closely attended to. "

"When, bhikkhus, the concentration by mindfulness of breathing has been developed and cultivated in this way, if he feels a pleasant feeling, he understands: 'It is impermanent'; he understands: 'It is not held to'; he understands: 'It is not delighted in.' If he feels a painful feeling, he understands: 'It is impermanent'; he understands: 'It is not held to'; he understands: 'It is not delighted in.' If he feels a neither-painful-nor-pleasant feeling, he understands: 'It is impermanent'; he understands: 'It is not held to'; he understands: 'It is not delighted in: "If he feels a pleasant feeling, he feels it detached; if he feels a painful feeling, he feels it detached; if he feels a neither-painful-nor-pleasant feeling, he feels it detached. "

"When he feels a feeling terminating with the body, he understands: 'I feel a feeling terminating with the body.' When he feels a feeling terminating with life, he understands: 'I feel a feeling terminating with life.' He understands: 'With the breakup of the body, following the exhaustion of life, all that is felt, not being delighted in, will become cool right here.' "

"Just as, bhikkhus, an oil lamp burns in dependence on the oil and the wick, and with the exhaustion of the oil and the wick it is extinguished through lack of fuel, so too, bhikkhus, when a bhikkhu feels a feeling terminating with the body ... terminating with life ... He understands: 'With the breakup of the body, following the exhaustion of life, all that is felt, not being delighted in, will become cool right here. "' 

(Before his awakening the Buddha generally practiced breath meditation, which kept him alert and peaceful and let to the ending of defilements. One who wishes for any of the higher fruits of the renunciate life should practice the same way.)

SN 54.​9 Vesālī Sutta: At Vesali

Thus have I heard. On one occasion the Blessed One was dwelling at Vesali in the Great Wood in the Hall with the Peaked Roof. Now on that occasion the Blessed One was giving the bhikkhus a talk on foulness in many ways, was speaking in praise of foulness, was speaking in praise of the development of foulness meditation. Then the Blessed One addressed the bhikkhus thus: "Bhikkhus, I wish to go into seclusion for half a month. I should not be approached by anyone except the one who brings me alms food."

"Yes, venerable sir," those bhikkhus replied, and no one approached the Blessed One except the one who brought him alms food. Then those bhikkhus, thinking: The Blessed One was giving a talk on foulness in many ways, was speaking in praise of foulness, was speaking in praise of the development of foulness meditation," dwelt devoted to the development of foulness meditation in its many aspects and factors. Being repelled, humiliated, and disgusted with this body, they sought for an assailant.

In one day ten bhikkhus used the knife, or in one day twenty or thirty bhikkhus used the knife. Then, when that half-month had passed, the Blessed One emerged from seclusion and addressed the Venerable Ananda: "Why, Ananda, does the Bhikkhu Sangha look so diminished?"
"Venerable sir, that is because [the Blessed One had given a talk on foulness in many ways, had spoken in praise of foulness, had spoken in praise of the development of foulness meditation, and those bhikkhus, thinking: 'The Blessed One was giving a talk on foulness in many ways, was speaking in praise of foulness, was speaking in praise of the development of foul meditation,' dwelt devoted to the development of foulness meditation in its many aspects and factors. Being repelled, humilated, and disgusted with this body, they sought for an assailant. In one day ten bhikkhus used the knife, or in one day twenty n thirty bhikkhus used the knife. It would be good, venerable Sir, if  the Blessed One would explain another method so that this Bhikkhu Sangha may be established in final knowledge."

"Well then, Ananda, assemble in the attendance hall all the bhikkhus who are living in dependence on Vesali."
"Yes, venerable sir," the Venerable Ananda replied, and he assembled in the attendance hall all the bhikkhus who were living in dependence on Vesali, as many as there were. Then he approached the Blessed One and said to him: "The Bhikkhu Sangha has assembled, venerable sir. Let the Blessed One come at his own convenience."

Then the Blessed One went to the attendance hall, sat down in the appointed seat, and addressed the bhikkhus thus: "Bhikkhus, this concentration by mindfulness of breathing, when developed and cultivated, is peaceful and sublime, an ambrosial pleasant dwelling, and it disperses and quells right on the spot evil unwholesome states whenever they arise."

"Just as, bhikkhus, in the last month of the hot season, when a mass of dust and dirt has swirled up, a great rain cloud out -of season disperses it and quells it on the spot, so too concentration by mindfulness of breathing, when developed and cultivated, is peaceful and sublime, an ambrosial pleasant dwelling, and it disperses and quells on the spot evil unwholesome states whenever they arise. And how is this so? "

"Here, bhikkhus, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes out. ... He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out.' "

"It is in this way, bhikkhus, that concentration by mindfulness of breathing is developed and cultivated so that it is peaceful and sublime, an ambrosial pleasant dwelling, and it disperses and quells on the spot evil unwholesome states whenever they arise." 

(The Buddha taught the meditation on the ugliness of the body, then left to go on retreat. However, many monks, misconstruing the teachings, ending up killing themselves. The Buddha taught breath meditation as a peaceful and pleasant abiding.)

SN 54.10 Kimila Sutta: Kimbila

Thus have I heard. On one occasion the Blessed One was dwelling at Kimbila in the Bamboo Grove. There the Blessed One addressed the Venerable Kimbila thus: "How is it now, Kimbila, that concentration by mindfulness of breathing is developed and cultivated so that it is of great fruit and benefit?"

When this was said, the Venerable Kimbila was silent. A second time ... A third time the Blessed One addressed the Venerable Kimbila: "How is it now, Kimbila, that concentration by mindfulness of breathing is developed and cultivated so that it is of great fruit and benefit?" A third time the Venerable Kimbila was silent.

When this happened, the Venerable Ananda said to the Blessed One: "Now is the time for this, Blessed One! Now is the time for this, Fortunate One! The Blessed One should speak on concentration by mindfulness of breathing. Having heard it from the Blessed One, the bhikkhus will remember it."
"Well then, Ananda, listen and attend closely, I will speak."
"Yes, venerable sir," the Venerable Ananda replied.

The Blessed One said this: "And how, Ananda, is concentration by mindfulness of breathing developed and cultivated so that it is of great fruit and benefit? Here, Ananda, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes out.... He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out.'

(i. Contemplation of the body)

"Whenever,Ananda, a bhikkhu, when breathing in long, knows: 'I breathe in long'; or, when breathing out long, knows: 'I breathe out long'; when breathing in short, knows: 'I breathe in short'; or, when breathing out short, knows: 'I breathe out short'; When he trains thus: 'Experiencing the whole body, I will breathe in'; when he trains thus: 'Experiencing the whole body, I will breathe out'; when he trains thus: 'Tranquilizing the bodily formation, I will breathe in'; when he trains thus: 'Tranquilizing the ​bodily formation, I will breathe out'-on that occasion bhikkhu dwells contemplating the body in the body, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. For what reason?I call this a certain kind of body, Ananda, that is, breathing in :d breathing out. Therefore, Ananda, on that occasion the bhikkhu dwells contemplating the body in the body, ardent clearly comprehending, mindful, having removed covetousnes and displeasure in regard to the world.

(ii. Contemplation of feelings)

"Whenever, Ananda, a bhikkhu trains thus: 'Experiencing rapture, I will breathe in'; when he trains thus: 'Experiencing rapture, I will breathe out'; when he trains thus: 'Experiencing happiness, I will breathe in'; when he trains thus: 'Experiencing happiness, I will breathe out'; when he trains thus: 'Experiencing the mental formation, I will breathe in'; when he trains thus: 'Experiencing the mental formation, I will breathe out'; when he trains thus: 'Tranquilizing the mental formation, I will breathe in'; when he trains thus: 'Tranquilizing the mental formation, I will breathe out'-on that occasion the bhikkhu dwells contemplating feelings in feelings, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. For what reason? I call this a certain kind of feeling, Ananda, that is, close attention to breathing in and breathing out. Therefore, Ananda, on that occasion the bhikkhu dwells contemplating feelings in feelings, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world.

(iii. Contemplation of mind)

"Whenever, Ananda, a bhikkhu trains thus: 'Experiencing the mind, I will breathe in'; when he trains thus: 'Experiencing the mind, I will breathe out'; when he trains thus: 'Gladdening the mind, I will breathe in'; when he trains thus: 'Gladdening the mind, I will breathe out'; when he trains thus: 'Concentrating the mind, I will breathe in'; when he trains thus: 'Concentrating the mind, I will breathe out'; when he trains thus: 'Liberating the mind, I will breathe in'; when he trains thus: 'Liberating the mind, I will breathe out'-on that occasion the bhikkhu dwells
 contemplating mind in mind, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. For what reason? I say, Ananda, that there is no development of concentration by mindfulness of breathing for one who is muddled and who lacks clear comprehension. Therefore, Ananda, on that occasion the bhikkhu dwells contemplating mind in mind, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world.

(iv. Contemplation of phenomena)

"Whenever, .Ananda, a bhikkhu trains thus: 'Contemplating impermanence, I will breathe in'; when he trains thus: 'Contemplating impermanence, I will breathe out'; when he trains thus: 'Contemplating fading away, I will breathe in'; when he trains thus: 'Contemplating fading away, I will breathe out'; when he trains thus: 'Contemplating cessation, I will breathe in'; when he trains thus: 'Contemplating cessation, I will breathe out'; when he trains thus: 'Contemplating relinquishment, I will breathe in'; when he trains thus: 'Contemplating relinquishment, I will breathe out' -on that occasion the bhikkhu dwells contemplating phenomena in phenomena, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. Having seen with wisdom the abandoning of covetousness and displeasure, he is one who looks on closely with equanimity.

Therefore, Ananda, on that occasion the bhikkhu dwells contemplating phenomena in phenomena, ardent, dearly comprehending, mindful, having removed covetousness and displeasure in regard to the world.

"Suppose, .Ananda, at a crossroads there is a great mound of soil. If a cart or chariot comes from the east, west, north, or south, it would flatten that mound of Soil. So too, Ananda, when a bhikkhu dwells contemplating the body in the body, feelings in feelings, mind in mind, phenomena in phenomena, he flattens evil unwholesome states." 

(When the Buddha asks Venerable Kimbila about breath meditation, he is unable to answer. At Ānanda’s urging, the Buddha explains in detail.)

SN 54.11 Icchānaṅgala Sutta: At Icchanangala 

On one occasion the Blessed One was dwelling at Icchanangala in the Icchanangala Wood. There the Blessed One addressed the bhikkhus thus: "Bhikkhus, I wish to go into seclusion for three months. I should not be approached by anyone except the one who brings me alms food."

"Yes, venerable sir," those bhikkhus replied, and no one approached the Blessed One except the one who brought him alms food.Then, when those three months had passed, the Blessed One emerged from seclusion and addressed the bhikkhus thus: "Bhikkhus, if wanderers of other sects ask you: 'In what dwelling, friends, did the Blessed One generally dwell during the rains residence?'-being asked thus, you should answer those wanderers thus: 'During the rains residence, friends, the Blessed One generally dwelt in the concentration by mindfulness of breathing.' "
​
"Here, bhikkhus, mindful I breathe in, mindful I breathe out. When breathing in long I know: 'I breathe in long'; when breathing out long I know: 'I breathe out long. ' When breathing in short I know: 'I breathe in short'; when breathing out short I know: 'I breathe out short.' I know: 'Experiencing the whole body I will breathe in.' ... I know: 'Contemplating relinquishment, I will breathe out.'"

"If anyone, bhikkhus, speaking rightly could say of anything: 'It is a noble dwelling, a divine dwelling, the Tathagata's dwelling,' it is of concentration by mindfulness of breathing that one could rightly say this. "Bhikkhus, those bhikkhus who are trainees, who have not attained their mind's ideal, who dwell aspiring for the unsurpassed security from bondage: for them concentration by mindfulness of breathing, when developed and cultivated, leads to the destruction of the taints. Those bhikkhus who are arahants, whose taints are destroyed, who have lived the holy life, done what had to be done, laid down the burden, reached their own goal, utterly destroyed the fetters of existence, those completely liberated through final knowledge: for them concentration by mindfulness of breathing, when developed and cultivated, leads to a pleasant dwelling in this very life and to mindfulness and clear comprehension."

"If anyone, bhikkhus, speaking rightly could say of anything: 'It is a noble dwelling, a divine dwelling, the Tathagata's dwelling,' it is of concentration by mindfulness of breathing that one could rightly say this." 

(The Buddha goes on a three month retreat, and later says that during that time he mostly practiced breath meditation.)

​SN 54.12 Kaṅkheyya Sutta: In Perplexity

On one occasion the Venerable Lomasavangisa was dwelling among the Sakyans at Kapilavatthu in Nigrodha's Park. Then Mahanama the Sakyan approached the Venerable Lomasavangisa, paid homage to him, sat down to one side, and said to him: "Is it the case, venerable sir, that the dwelling of a trainee is itself the same as the Tathagata's dwelling, or is it rather that the dwelling of a trainee is one thing and the Tathagata's dwelling is another?"

"It is not the case, friend Mahanama, that the dwelling of a trainee is itself the same as the Tathagata's dwelling; rather, the dwelling of a trainee is one thing and the Tathagata's dwelling is another. "Friend Mahanama, those bhikkhus who are trainees, who have not attained their mind's ideal, who dwell aspiring for the unsurpassed security from bondage, dwell having abandoned the five hindrances. What five? The hindrances of sensual desire, ill will, sloth and torpor, restlessness and remorse, and doubt. Those bhikkhus who are trainees ... dwell having abandoned these five hindrances. "

"But, friend Mahanama, for those bhikkhus who are arahants, whose taints are destroyed, who have lived the holy life, done what had to be done, laid down the burden, reached their own goal, utterly destroyed the fetters of existence, become completely liberated through final knowledge, the five hindrances have been abandoned, cut off at the root, made like palm stumps, obliterated so that they are no more subject to future arising. What five? The hindrances of sensual desire, ill will, sloth and torpor, restlessness and remorse, and doubt. For the bhikkhus who are arahants ... these five hindrances have been abandoned, cut off at the root, made like palm stumps obliterated so that they are no more subject to future arising. "

"By the following method too, friend Mahanama, it can be understood how the dwelling of a trainee is one thing and the Tathagata's dwelling is another."

On this one occasion, friend Mahanama, the Blessed One was dwelling at Icchanangala in the Icchanangala Wood. There the Blessed One addressed the bhikkhus thus: 'Bhikkhus, I Wish to go into seclusion for three months. I should not be approached by anyone except the one who brings me alms food.'

(He here repeats the entire contents of the preceding sutta, down to) "
'If anyone, bhikkhus, speaking rightly could say of anything: "It is a noble dwelling, a divine dwelling, the Tathagata's dwelling," it is of concentration by mindfulness of breathing that one could rightly say this.' "

"By this method, friend Mahanama, it can be understood how the dwelling of a trainee is one thing and the Tathagata's dwelling is another."

(Venerable Lomasavaṅgīsa explains to Mahānāma that the difference between a trainee and the Realized One is that the trainees practice to give up the hindrances, whereas the Realized One has already ended all defilements.)

SN 54.13 Paṭhamaānanda Sutta: Ananda (1)

At Savatthi. Then the Venerable Ananda approached the Blessed One, paid homage to him, sat down to one side, and said to him: "Venerable sir, is there one thing which, when developed and cultivated, fulfills four things? And four things which, when developed and cultivated, fulfill seven things? And seven things which, when developed and cultivated, fulfill two things?"

"There is, Ananda, one thing which, when developed and cultivated, fulfills four things; and four things which, when developed and cultivated, fulfill seven things; and seven things which, when developed and cultivated, fulfill two things."

"But, venerable sir, what is the one thing which, when developed and cultivated, fulfills four things; and the four things which, when developed and cultivated, fulfill seven things; and the seven things which, when developed and cultivated, fulfill two things?"

​"Concentration by mindfulness of breathing, Ananda, is the one thing which, when developed and cultivated, fulfills the four establishments of mindfulness. The four establishments of mindfulness, when developed and cultivated, fulfill the seven factors of enlightenment. The seven factors of enlightenment, when developed and cultivated, fulfill true knowledge and liberation. "

(i. Fulfilling the four establishments of mindfulness)

"How, Ananda, is concentration by mindfulness of breathing developed and cultivated so that it fulfills the four establishments of mindfulness? Here, Ananda, a bhikkhu, having gone to the forest, to the foot of a tree, or to an empty hut, sits down. Having folded his legs crosswise, straightened his body, and set up mindfulness in front of him, just mindful he breathes in, mindful he breathes out .... He trains thus: 'Contemplating relinquishment, I will breathe in'; he trains thus: 'Contemplating relinquishment, I will breathe out.' "

"Whenever, Ananda, a bhikkhu, when breathing in long, knows: 'I breathe in long' ... (as in §1O) ... when he trains thus: 'Tranquilizing the bodily formation, I will breathe out' -on that occasion the bhikkhu dwells contemplating the body in the body, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. For what reason? I call this a certain kind of body, Ananda, that is, breathing in and breathing out. Therefore, Ananda, on that occasion the bhikkhu dwells contemplating the body in the body, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world."

"Whenever, Ananda, a bhikkhu trains thus: 'Experiencing rapture, I will breathe in' ... when he trains thus: 'Tranquilizing the mental formation, I will breathe out' --on that occasion the bhikkhu dwells contemplating feelings in feelings, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. For what reason? I call this a certain kind of feeling, Ananda, that is, close attention to breathing in and breathing out. Therefore, Ananda, on that occasion the bhikkhu dwells contemplating feelings in feelings, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. "

"Whenever, Ananda, a bhikkhu trains thus: 'Experiencing the mind, I will breathe in' ... when he trains thus: 'Liberating the mind, I will breathe out' -on that occasion the bhikkhu dwells contemplating mind in mind, ardent, clearly comprehend' mindful, having removed covetousness and displeasure in regard to the world. For what reason? I say, Ananda that there is no development of concentration by mindfulness of breathing for one who is muddled and who lacks clear comprehension. Therefore, Ananda, on that occasion the bhikkhu dwells contemplating mind in mind, ardent, clearly comprehending, mindful having removed covetousness and displeasure in regard to the world. "

"Whenever, Ananda, a bhikkhu trains thus: 'Contemplating impermanence, I will breathe in' .. , when he trains thus: 'Contemplating relinquishment, I will breathe out' -on that occasion the bhikkhu dwells contemplating phenomena in phenomena, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. Having seen with wisdom what is the abandoning of covetousness and displeasure, he is one who looks on closely with equanimity. Therefore, Ananda, on that occasion the bhikkhu dwells contemplating phenomena in phenomena, ardent, dearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. "

"It is, Ananda, when concentration by mindfulness of breathing is developed and cultivated in this way that it fulfills the four establishments of mindfulness."

(ii. Fulfilling the seven factors of enlightenment)

"And how, Ananda, are the four establishments of mindfulness developed and cultivated so that they fulfill the seven factors of enlightenment? "

"Whenever, Ananda, a bhikkhu dwells contemplating the body in the body, on that occasion unmuddled mindfulness is established in that bhikkhu. Whenever, Ananda, unmuddled mindfulness has been established in a bhikkhu, on that occasion the enlightenment factor of mindfulness is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of mindfulness; on that occasion the enlightenment factor of mindfulness goes to fulfillment by development in the bhikkhu. "

"Dwelling thus mindfully, he discriminates that Dhamma with ​wisdom, examines it, makes an investigation of it. Whenever, Ananda, a bhikkhu dwelling thus mindfully discriminates that Dhamma with wisdom, examines it, makes an investigation of it, on that occasion the enlightenment factor of discrimination of states is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of discrimination of states; on that occasion the enlightenment factor of discrimination of states goes to fulfilment by development in the bhikkhu."

"While he discriminates that Dhamma with wisdom, examines it, makes an investigation of it, his energy is aroused without slackening. Whenever, Ananda, a bhikkhu's energy is aroused without slackening as he discriminates that Dhamma with wisdom, examines it, makes an investigation of it, on that occasion the enlightenment factor of energy is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of energy; on that occasion the enlightenment factor of energy goes to fulfillment by development in the bhikkhu. "

​"When his energy is aroused, there arises in him spiritual rapture. Whenever, Ananda, spiritual rapture arises in a bhikkhu whose energy is aroused, on that occasion the enlightenment factor of rapture is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of rapture; on that occasion the enlightenment factor of rapture goes to fulfillment by development in the bhikkhu. "

"For one whose mind is uplifted by rapture the body becomes tranquil and the mind becomes tranquil. Whenever, Ananda, the body becomes tranquil and the mind becomes tranquil in a bhikkhu whose mind is uplifted by rapture, on that occasion the enlightenment factor of tranquility is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of tranquility; on that occasion the enlightenment factor of tranquility goes to fulfillment by development in the bhikkhu. "

"For one whose body is tranquil and who is happy the mind becomes concentrated. Whenever, Ananda, the mind becomes concentrated in a bhikkhu whose body is tranquil and who is happy, on that occasion the enlightenment factor of concentration is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of concentration; on that occasion the enlightenment factor of concentration goes to fulfillment by development in the bhikkhu. ​"

"He becomes one who closely looks on with equanimity at the mind thus concentrated. Whenever, Ananda, a bhikkhu becomes one who closely looks on with equanimity at the mind thus Concentrated, on that occasion the enlightenment factor of equanimity is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of equanimity; on that occasion the enlightenment factor of equanimity goes to fulfillment by development in the bhikkhu. "

"Whenever, Ananda, a bhikkhu dwells contemplating feelings in feelings ... mind in mind .,. phenomena in phenomena, on that occasion unmuddled mindfulness is established in that bhikkhu. Whenever, Ananda, unmuddled mindfulness has been established in a bhikkhu, on that occasion the enlightenment factor of mindfulness is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of mindfulness; on that occasion the enlightenment factor of mindfulness goes to fulfillment by development in the bhikkhu. "
(All should be elaborated as in the case of the first establishment of mindfulness. )

"He becomes one who closely looks on with equanimity at the mind thus concentrated. Whenever, Ananda, a bhikkhu becomes one who closely looks on with equanimity at the mind thus concentrated, on that occasion the enlightenment factor of equanimity is aroused by the bhikkhu; on that occasion the bhikkhu develops the enlightenment factor of equanimity; on that occasion the enlightenment factor of equanimity goes to fulfillment by development in the bhikkhu. "

"It is, Ananda, when the four establishments of mindfulness are developed and cultivated in this way that they fulfill the seven factors of enlightenment."

(iii. Fulfilling true knowledge and liberation)

"How, Ananda, are the seven factors of enlightenment developed and cultivated so that they fulfill true knowledge and liberation? "

"Here, Ananda, a bhikkhu develops the enlightenment factor of mindfulness, which is based upon seclusion, dispassion, and cessation, maturing in release. He develops the enlightenment factor of discrimination of states ... the enlightenment factor of energy ... the enlightenment factor of rapture ... the enlightenment factor of tranquility ... the enlightenment factor of concentration ... the enlightenment factor of equanimity, which is based upon seclusion, dispassion, and cessation, maturing in release. "

"It is, Ananda, when the seven factors of enlightenment are developed and cultivated in this way that they fulfill true knowledge and liberation."

(Answering Ānanda, the Buddha explains how one thing fulfills four things, four things fulfill seven things, and seven things fulfill two things.)

The Blessed One then said to the Venerable Ananda: "Ananda, is there one thing which, when developed and cultivated, fulfills four things?
