Kalyāṇamitta sutta: Good Friends (1st)

At Sāvatthī.

“Mendicants, the dawn is the forerunner and harbinger of the sunrise. In the same way good friendship is the forerunner and harbinger of the noble eightfold path for a mendicant. A mendicant with good friends can expect to develop and cultivate the noble eightfold path.

And how does a mendicant with good friends develop and cultivate the noble eightfold path? It’s when a mendicant develops right view, right purpose, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion, which rely on seclusion, fading away, and cessation, and ripen as letting go. That’s how a mendicant with good friends develops and cultivates the noble eightfold path.”
