Aññatarabhikkhusutta
Atha kho aññataro bhikkhu yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavantaṁ abhivādetvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho so bhikkhu bhagavantaṁ etadavoca: “katamā nu kho, bhante, vedanā, katamo vedanāsamudayo, katamā vedanāsamudayagāminī paṭipadā? Katamo vedanānirodho, katamā vedanānirodhagāminī paṭipadā? Ko vedanāya assādo, ko ādīnavo, kiṁ nissaraṇan”ti?

What’s the cessation of feeling? What’s the practice that leads to the cessation of feeling? And what is feeling’s gratification, drawback, and escape?”
