1At Sāvatthī.

“Mendicants, one thing helps give rise to the noble eightfold path. What one thing? It’s good friendship. 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 thought, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion, which culminate in the removal of greed, hate, and delusion. That’s how a mendicant with good friends develops and cultivates the noble eightfold path.”

1Sāvatthi­nidānaṁ.

"Ekadhammo, bhikkhave, bahūpakāro ariyassa aṭṭhangikassa maggassa uppādāya. Katamo ekadhammo? Yadidaṁ – kalyāṇamittatā. Kalyāṇamittassetaṁ, bhikkhave, bhikkhuno pāṭikankhaṁ – ariyaṁ aṭṭhangikaṁ maggaṁ bhāvessati, ariyaṁ aṭṭhangikaṁ maggaṁ bahulīkarissati.

Kathañca, bhikkhave, bhikkhu kalyāṇamitto ariyaṁ aṭṭhangikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhangikaṁ maggaṁ bahulīkaroti? Idha, bhikkhave, bhikkhu sammādiṭṭhiṁ bhāveti rāgavinayapari­yosānaṁ dosavinayapariyosānaṁ mohavinayapariyosānaṁ … pe … sammāsamādhiṁ bhāveti rāgavinayapari­yosānaṁ dosavinayapariyosānaṁ mohavinayapariyosānaṁ. Evaṁ kho, bhikkhave, bhikkhu kalyāṇamitto ariyaṁ aṭṭhangikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhangikaṁ maggaṁ bahulīkarotī"ti.

Paṭhamaṁ.
