“Sūriyassa, bhikkhave, udayato etaṁ pubbaṅgamaṁ etaṁ pubbanimittaṁ, yadidaṁ—aruṇuggaṁ; evameva kho, bhikkhave, bhikkhuno sattannaṁ bojjhaṅgānaṁ uppādāya etaṁ pubbaṅgamaṁ etaṁ nimittaṁ, yadidaṁ—kalyāṇamittatā. Kalyāṇamittassetaṁ, bhikkhave, bhikkhuno pāṭikaṅkhaṁ—satta bojjhaṅge bhāvessati, satta bojjhaṅge bahulīkarissati.

The Simile of the Sun (1st)

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

Kathañca, bhikkhave, bhikkhu kalyāṇamitto satta bojjhaṅge bhāveti satta bojjhaṅge bahulīkaroti? Idha, bhikkhave, bhikkhu satisambojjhaṅgaṁ bhāveti vivekanissitaṁ …pe… upekkhāsambojjhaṅgaṁ bhāveti vivekanissitaṁ virāganissitaṁ nirodhanissitaṁ vossaggapariṇāmiṁ. Evaṁ kho, bhikkhave, bhikkhu kalyāṇamitto satta bojjhaṅge bhāveti, satta bojjhaṅge bahulīkarotī”ti.

And how does a mendicant with good friends develop and cultivate the seven awakening factors? It’s when a mendicant develops the awakening factors of mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity, 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 seven awakening factors.”
