Ud 5.7

Kaṅkhārevatasutta

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

With Revata the Doubter

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 Revata the Doubter was sitting not far from the Buddha, cross-legged, with his body straight, reviewing his own purification by traversing doubt.

Addasā kho bhagavā āyasmantaṁ kaṅkhārevataṁ avidūre nisinnaṁ pallaṅkaṁ ābhujitvā ujuṁ kāyaṁ paṇidhāya attano kaṅkhāvitaraṇavisuddhiṁ 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:

“Yā kāci kaṅkhā idha vā huraṁ vā, Sakavediyā vā paravediyā vā; Ye jhāyino tā pajahanti sabbā, Ātāpino brahmacariyaṁ carantā”ti.

“Any doubts about this life or the next, about one’s own experiences or those of another: those who meditate give them all up, keenly practicing the spiritual life.”
