In the Land of the VajjisVajjīsutta

At one time the Buddha was staying in the land of the Vajjis at Elephant Village.Ekaṁ samayaṁ bhagavā vajjīsu viharati hatthigāme. Then the householder Uggata of Elephant Village went up to the Buddha, sat down to one side, and said to him:Atha kho uggo gahapati hatthigāmako yena bhagavā tenupasaṅkami; upasaṅkamitvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho uggo gahapati hatthigāmako 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?
