​MN 9: Sammaditthi Sutta (Right View)

Thus i have heard. 

On one occasion the Blessed One was living at Savatthi in Jeta's Grove, Anathapindika's Park. There the Venerable Sariputta addressed the bhikkhus thus: "Friends, bhikkhus. One of right view, one of right view', it is said. In what way is a noble disciple one of right view, whose view is straight, who has perfect confidence in the Dhamma, and has arrived at this true Dhamma?
Monks: "Indeed friend, we would come from far away to learn from the venerable Sariputta the meaning of this statement. It would be good if the venerable Sariputta would explain the meaning of this statement. Having heard it from him, the bhikkhus will remember it."
Venerable Sariputta: "Then friends, listen attentively to what I shall say."

THE WHOLESOME AND THE UNWHOLESOME

Venerable Sariputta: "When friends, a noble disciple understands the unwholesome and the root of the unwholesome, the wholesome and the root of the wholesome,in that way he is one of right view, whose view is straight, who has perfect confidence in the Dhamma and has arrived at this true Dhamma. What is the unwholesome, what is the root of the unwholesome, what is the wholesome, what is the root of the wholesome?
What is Unwholesome: Killing living, taking what is not given, sexual misconduct, false speech, malicious speech, harsh speech, gossip , covetousness, ill will and wrong view is unwholesome.
What is the root of the unwholesome? Greed, hatred and delusion are roots of the unwholesome.
What is the wholesome: Abstention from killing living beings, abstention from taking what is not given, abstention from sexual misconduct, abstention from false speech, abstention from malicious speech, abstention from harsh speech, abstention from gossip, uncovetousness, non-ill will, right view is wholesome.
What is the root of the wholesome? Non-greed, non-hatred and non-delusion are roots of the wholesome.

"When a noble disciple has thus understood the unwholesome and the root of the unwholesome, the wholesome and the root of the wholesome, he entirely abandons the underlying tendency to lust, to aversion, to the view and conceit 'I am,' and by abandoning ignorance and arousing true knowledge he here and now makes an end of suffering. In that way too a noble disciple is one of right view, whose view is straight, who has perfect confidence in the Dhamma, and has arrived at this true Dhamma." 

NUTRIMENT

The bhikkhus delighted and rejoiced in the Venerable Sariputta's words. Then they asked him a further question: "Is there another way in which a noble disciple is one of right view...and has arrived at this true Dhamma?"
Venerable Sariputta: "There might be, friends. When, friends, a noble disciple understand nutriment, the origin of nutriment, the cessation of nutriment, and the way leading to the cessation of nutriment, in that way he is one of right view.. .and has arrived at this true Dhamma."

What is nutriment, what is the origin of nutriment, what is the cessation of nutriment, what is the way leading to the cessation of nutriment? There are four kinds of nutriment for the maintenance of beings that already have come to be and for the support of those seeking a new existence. What four? They are: physical food as nutriment, contact as the second; mental volition as the third and consciousness as the fourth. With the arising of craving there is the arising of nutriment. With the cessation of craving there is the cessation of nutriment. The way leading to the cessation of nutriment is just this Noble Eightfold Path which consists of right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration.

"When a noble disciple has thus understood nutriment, the origin of nutriment, the cessation of nutriment and the way leading to the cessation of nutriment, he entirely abandons the underlying tendency to greed, he abolishes the underlying tendency to aversion, he extirpates the underlying tendency to the view and conceit "I am" and by abandoning ignorance and arousing true knowledge he here and now makes an end of suffering. In that way too a noble disciple is one of right view, whose view is straight, who has perfect confidence in the Dhamma, and has arrived at this true Dhamma." 

THE FOUR NOBLE TRUTHS

The bhikkhus delighted and rejoiced in the Venerable Sariputta's words. Then they asked him a further question: "Is there another way in which a noble disciple is one of right view...and has arrived at this true Dhamma?"

"And what is suffering, what is the origin of suffering, what is the cessation of suffering, what is the way leading to the cessation of suffering?
Suffering: Birth is suffering; ageing is suffering; sickness is suffering; death is suffering; sorrow, lamentation, pain, grief, and despair are suffering; not to obtain what one wants is suffering; in short, the five aggregates affected by clinging are suffering. This is called suffering.
Origin of suffering: It is craving, which brings renewal of being, is accompanied by delight and lust, and delights in this and that; that is, craving for sensual pleasures, craving for being, and craving for non-being. This is called the origin of suffering.
Cessation of suffering: It is the fading away and ceasing, the giving up, relinquishing, letting go and rejecting of that same craving. This is called the cessation of suffering. 1
Way leading to the cessation of suffering: It is just this Noble Eightfold Path

"When a noble disciple has thus understood suffering, the origin of suffering, the cessation of suffering, and the way leading to the cessation of suffering.. .he here and now makes an end of suffering. In that way too a noble disciple is one of right view...and has arrived at this true Dhamma."

In summary, in this sutta Venerable Sariputta addressed an assembly of monks to talk about "Right view" which is the forerunner of the noble eightfold path. Noble eightfold path is the path taught by the Buddha that will lead to cessation of suffering. 
Venerable Sariputta talked about the following 16 cases through which a noble disciple could achieve right view:
  • the Unwholesome and the Wholesome 
  • Nutriments
  • the Four Noble Truths
  • the twelve links of Dependent Origination in reverse order
  • the Taints
Right view is achieved for these cases by understanding the four phases of each case:
  • the constituents of the case
  • its origin
  • its cessation
  • the way leading to its cessation
