Sāriputta and the Protégé 2.3

2.3

‘So vatāvuso, bhikkhu indriyesu guttadvāro, bhojane mattaññū, jāgariyaṃ anuyutto yāvajīvaṃ paripuṇṇaṃ parisuddhaṃ brahmacariyaṃ santānessatī’ti ṭhānametaṃ vijjati.

But it is quite possible for a mendicant to maintain the full and pure spiritual life for the rest of their life if they guard the sense doors, eat in moderation, and are committed to wakefulness.
