1"Bhikkhus, sn.v.37I do not see even one other thing by means of which the unarisen Noble Eightfold Path arises and the arisen Noble Eightfold Path goes to fulfilment by development so effectively as by this: good friendship. When a bhikkhu has a good friend, it is to be expected that he will develop and cultivate the Noble Eightfold Path.

"And how, bhikkhus, does a bhikkhu who has a good friend develop and cultivate the Noble Eightfold Path?

Here, bhikkhus, a bhikkhu develops right view, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.
He develops right intention, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.
He develops right speech, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.
He develops right action, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.
He develops right livelihood, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.
He develops right effort, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.
He develops right mindfulness, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.
He develops right concentration, which has as its final goal the removal of lust, the removal of hatred, the removal of delusion.

It is in this way that one who has a good friend develops and cultivates the Noble Eightfold Path."
