Acelakassapasutta
Evaṁ me sutaṁ— ekaṁ samayaṁ bhagavā rājagahe viharati veḷuvane kalandakanivāpe. Atha kho bhagavā pubbaṇhasamayaṁ nivāsetvā pattacīvaramādāya rājagahaṁ piṇḍāya pāvisi. Addasā kho acelo kassapo bhagavantaṁ dūratova āgacchantaṁ. Disvāna yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavatā saddhiṁ sammodi. Sammodanīyaṁ kathaṁ sāraṇīyaṁ vītisāretvā ekamantaṁ aṭṭhāsi. Ekamantaṁ ṭhito kho acelo kassapo bhagavantaṁ etadavoca: “puccheyyāma mayaṁ bhavantaṁ gotamaṁ kañcideva desaṁ, sace no bhavaṁ gotamo okāsaṁ karoti pañhassa veyyākaraṇāyā”ti. “Akālo kho tāva, kassapa, pañhassa; antaragharaṁ paviṭṭhamhā”ti.
With Kassapa, the Naked Ascetic
So I have heard. At one time the Buddha was staying near Rājagaha in the Bamboo Grove, the squirrels’ feeding ground. Then the Buddha robed up in the morning and, taking his bowl and robe, entered Rājagaha for alms. The naked ascetic Kassapa saw the Buddha coming off in the distance. He went up to the Buddha, and exchanged greetings with him. When the greetings and polite conversation were over, he stood to one side and said to the Buddha, “I’d like to ask the worthy Gotama about a certain point, if you’d take the time to answer.” “Kassapa, it’s the wrong time for questions. We’ve entered an inhabited area.”
