The Alms-GathererPiṇḍolasutta

So I have heard.Evaṁ me sutaṁ— At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery.ekaṁ samayaṁ bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme. Now at that time Venerable Bhāradvāja the Alms-Gatherer was sitting not far from the Buddha, cross-legged, with his body straight. He was one who lived in the wilderness, ate only almsfood, wore rag robes, and owned just three robes. He was of few wishes, content, secluded, aloof, and energetic, an advocate of austerities, dedicated to the higher mind.Tena kho pana samayena āyasmā piṇḍolabhāradvājo bhagavato avidūre nisinno hoti pallaṅkaṁ ābhujitvā ujuṁ kāyaṁ paṇidhāya āraññiko piṇḍapātiko paṁsukūliko tecīvariko appiccho santuṭṭho pavivitto asaṁsaṭṭho āraddhavīriyo dhutavādo adhicittamanuyutto.

The Buddha saw him meditating there.Addasā kho bhagavā āyasmantaṁ piṇḍolabhāradvājaṁ avidūre nisinnaṁ pallaṅkaṁ ābhujitvā ujuṁ kāyaṁ paṇidhāya āraññikaṁ piṇḍapātikaṁ paṁsukūlikaṁ tecīvarikaṁ appicchaṁ santuṭṭhaṁ pavivittaṁ asaṁsaṭṭhaṁ āraddhavīriyaṁ dhutavādaṁ adhicittamanuyuttaṁ.

Then, understanding this matter, on that occasion the Buddha expressed this heartfelt sentiment:Atha kho bhagavā etamatthaṁ viditvā tāyaṁ velāyaṁ imaṁ udānaṁ udānesi:

“Not speaking ill nor doing harm;“Anūpavādo anūpaghāto, restraint in the monastic code;Pātimokkhe ca saṁvaro; moderation in eating;Mattaññutā ca bhattasmiṁ, staying in remote lodgings;Pantañca sayanāsanaṁ; commitment to the higher mind—Adhicitte ca āyogo, this is the instruction of the Buddhas.”Etaṁ buddhāna sāsanan”ti.
