Ud 4.10

Sāriputtaupasamasutta

Evaṁ me sutaṁ— ekaṁ samayaṁ bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme. Tena kho pana samayena āyasmā sāriputto bhagavato avidūre nisinno hoti pallaṅkaṁ ābhujitvā ujuṁ kāyaṁ paṇidhāya attano upasamaṁ paccavekkhamāno.

The Peacefulness of Sāriputta

So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery. Now at that time Venerable Sāriputta was sitting not far from the Buddha, cross-legged, with his body straight, reviewing his own peacefulness.

Addasā kho bhagavā āyasmantaṁ sāriputtaṁ avidūre nisinnaṁ pallaṅkaṁ ābhujitvā ujuṁ kāyaṁ paṇidhāya attano upasamaṁ paccavekkhamānaṁ.

The Buddha saw him meditating there.

Atha kho bhagavā etamatthaṁ viditvā tāyaṁ velāyaṁ imaṁ udānaṁ udānesi:

Then, understanding this matter, on that occasion the Buddha expressed this heartfelt sentiment:

“Upasantasantacittassa, netticchinnassa bhikkhuno; Vikkhīṇo jātisaṁsāro, mutto so mārabandhanā”ti.

“With mind at peace, so full of peace, for a mendicant who has cut the cord, transmigration through births is finished: they’re freed from Māra’s bonds.”
