With SoṇaSoṇasutta

At one time the Buddha was staying near Rājagaha in the Bamboo Grove, the squirrels’ feeding ground.Ekaṁ samayaṁ bhagavā rājagahe viharati veḷuvane kalandakanivāpe.

Then the householder Soṇa went up to the Buddha, bowed, sat down to one side, and said to him:Atha kho soṇo gahapatiputto yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavantaṁ abhivādetvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho soṇo gahapatiputto bhagavantaṁ etadavoca:

“What is the cause, sir, what is the reason why some sentient beings are not fully extinguished in this very life?“ko nu kho, bhante, hetu, ko paccayo yena m’idhekacce sattā diṭṭheva dhamme no parinibbāyanti? What is the cause, sir, what is the reason why some sentient beings are fully extinguished in this very life?” …Ko pana, bhante, hetu, ko paccayo yena m’idhekacce sattā diṭṭheva dhamme parinibbāyantī”ti?
