UD 7.7  Papañcakhaya sutta - Wearing Away of Mental Proliferation

Evaṁ me sutaṁ— ekaṁ samayaṁ bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme. Tena kho pana samayena bhagavā attano papañcasaññāsaṅkhāpahānaṁ paccavekkhamāno nisinno hoti.

Thus have I heard—At one time, the Blessed One was dwelling at Sāvatthi, in Jeta’s grove, Anāthapiṇḍika’s park. At that time, the Blessed One was seated, reflecting on his own |giving up of the perceptions and notions [born of] mental proliferation::abandoning the proliferation of opinions, concepts and constructs [papañcasaññāsaṅkhāpahāna]|.

Atha kho bhagavā attano papañcasaññāsaṅkhāpahānaṁ viditvā tāyaṁ velāyaṁ imaṁ udānaṁ udānesi:

Then, the Blessed One, having understood his own giving up of the perceptions and notions [born of] mental proliferation, at that time, expressed this inspired utterance:

“Yassa papañcā ṭhiti ca natthi,
Sandānaṁ palighañca vītivatto;
Taṁ nittaṇhaṁ muniṁ carantaṁ,
Nāvajānāti sadevakopi loko”ti.

“In whom, support for mental proliferation does not exist,
who has gone beyond tethers and barriers;
The sage who lives without |craving::wanting, yearning, longing, attachment, lit. thirst [taṇha]|,
is not despised by the world with its gods.”
