​MN 74 Dighanakha Sutta: To Dighanakha 

Thus have i heard.

On one occasion the Blessed One was living at Rajagaha in the Boar's Cave on the mountain Vulture Peak. Then the wanderer Dighanakha went to the Blessed One and exchanged greetings with him. He said to the Blessed One: "Master Gotama, my doctrine and view is this: 'Nothing is acceptable to me.'"
Buddha: "This view of yours, Aggivessana, 'Nothing is acceptable to me' - is not at least that view acceptable to you?"
Dighanakha: "If this view of mine were acceptable to me, Master Gotama, it too would be the same, it too would be the same."
Buddha: "Well, Aggivessana, there are plenty in the world who say: 'It too would be the same, it too would be the same,' yet they do not abandon that view and they take up still some other view. There are few in the world who say: 'It too would be the same, it too would be the same,' and who abandon that view and do not take up some other view."

"Aggivessana, there are some recluses and brahmins whose doctrine and view is this: 'Everything is acceptable to me.' There are some recluses and brahmins whose doctrine and view is this: 'Nothing is acceptable to me.' And there are some recluses and brahmins whose doctrine and view is this: 'Something is acceptable to me, something is not acceptable to me.' Among these, the view of those recluses and brahmins who hold the doctrine and view 'Everything is acceptable to me' is close to lust, close to bondage, close to delighting, close to holding, close to clinging. The view of those recluses and brahmins who hold the doctrine and view 'Nothing is acceptable to me' is close to non-lust, close to non-bondage, close to non-delighting, close to non-holding, close to non-clinging."

When this was said, the wanderer Dighanakha remarked: "Master Gotama commends my point of view, Master Gotama recommends my point of view."
Buddha: " Aggivessana, as to those recluses and brahmins who hold the doctrine and view 'Something is acceptable to me, something is not acceptable to me' - the view of theirs as to what is acceptable is close to lust, close to bondage, close to delighting, close to holding, close to clinging, while the view of theirs as to what is not acceptable is close to non-lust, close to non-bondage, close to non-delighting, close to non-holding, close to non-clinging. "

"Now, Aggivessana, a wise man among those recluses and brahmins who hold the doctrine and view 'Everything is acceptable to me' considers thus: 'If I obstinately adhere to my view "Everything is acceptable to me" and declare: "Only this is true, anything else is wrong," then I may clash with the two others: with a recluse or brahmin who holds the doctrine and view "Nothing is acceptable to me" and with a recluse or brahmin who holds the doctrine and view "Something is acceptable to me, something is not acceptable to me." I may clash with these two, and when there is a clash, there are disputes; when there are disputes, there are quarrels; when there are quarrels, there is vexation.' Foreseeing these clashes, disputes, quarrels, and vexation, he abandons that view and does not take up some other view. This is how there comes to be the abandoning of these views; this is how there comes to be the relinquishing of these views. "

Foreseeing these clashes, disputes, quarrels, and vexation, he abandons that view and does not take up some other view. This is how there comes to be the abandoning of these views; this is how there comes to be the relinquishing of these views. "

"Now Aggivessana, this body made of material form consists of the four great elements, procreated by a mother and father, and nourished with boiled rice and porridge, is subject to impermanence, to being worn and rubbed away, to dissolution and disintegration. It should be regarded as impermanent, as suffering, as a disease, as a tumor, as a calamity, as an affliction, as disintegrating, as void, as not self. When one regards this body thus one abandons desire for the body, affection for the body, subservience to the body."

"There are Aggivessana, three kinds of feeling: pleasant feeling, painful feeling, and neither-painful-nor-pleasant feeling. On the occasion when one feels pleasant feeling, one does not feel painful feeling or neither-painful-nor-pleasant feeling; on that occasion one feels only pleasant feeling. On the occasion when one feels painful feeling, one does not feel pleasant feeling or neither-painful-nor-pleasant feeling. On the occasion when one feels neither painful-nor-pleasant feeling, one does not feel pleasant feeling or painful feeling."

"Aggivessana,Pleasant feeling, painful feeling and neither-painful-nor-pleasant feeling are impermanent, conditioned, dependently arisen, subject to destruction, vanishing, fading away, and ceasing. " 

"Seeing thus, a well-taught noble disciple becomes disenchanted with pleasant feeling, disenchanted with painful feeling, disenchanted with neither-painful-nor-pleasant feeling. Being disenchanted, he becomes dispassionate. Through dispassion his mind is liberated. When it is liberated there comes the knowledge: 'It is liberated.' He understands: 'Birth is destroyed, the holy life has been lived, what had to be done has been done, there is no more coming to any state of being.'"

"A bhikkhu whose mind is liberated thus, Aggivessana, sides with none and disputes with none; he employs the speech currently used in the world without adhering to it."

Now on that occasion the venerable Sariputta was standing behind the Blessed One, fanning him. Then he thought: "The Blessed One, indeed, speaks of the abandoning of these things through direct knowledge and the relinquishing of these things through direct knowledge." As the venerable Sariputta considered this, through not clinging his mind was liberated from the taints.

Then in the wanderer Dighanakha the spotless immaculate vision of the Dhamma arose: "All that is subject to arising is subject to cessation." The wanderer Dighanakha saw the Dhamma, attained the Dhamma, understood the Dhamma, fathomed the Dhamma; he crossed beyond doubt, did away with perplexity, gained intrepidity, and became independent of others in the Teacher's Dispensation.Then he said to the Blessed One: "Magnificent, Master Gotama! Magnificent, Master Gotama! Master Gotama has made the Dhamma clear in many ways, as though he were turning upright what had been overthrown, revealing what was hidden, showing the way to one who was lost, or holding up a lamp in the dark for those with eyesight to see forms. I go to Master Gotama for refuge and to the Dhamma and to the Sangha of bhikkhus. From today let Master Gotama remember me as a lay follower who has gone to him for refuge for life." 

In summary, a wanderer Dighanakha told the Buddha that his doctrine and view is " Nothing is acceptable to me." 
Buddha gave him an instruction in the abandoning of points of view, detachment from body and non-clinging to feelings. when one is disenchanted from the 3 feelings namely pleasant, painful and neither pleasant nor painful then one becomes dispassionate and the mind is liberated. It is by listening to this sutta that Venerable Sariputta becomes arahant and Dighanakha becomes a Streamwinner.
