Devadahasutta
Evaṁ me sutaṁ— ekaṁ samayaṁ bhagavā sakkesu viharati devadahaṁ nāma sakyānaṁ nigamo. Atha kho sambahulā pacchābhūmagamikā bhikkhū yena bhagavā tenupasaṅkamiṁsu; upasaṅkamitvā bhagavantaṁ abhivādetvā ekamantaṁ nisīdiṁsu. Ekamantaṁ nisinnā kho te bhikkhū bhagavantaṁ etadavocuṁ: “icchāma mayaṁ, bhante, pacchābhūmaṁ janapadaṁ gantuṁ, pacchābhūme janapade nivāsaṁ kappetun”ti.
At Devadaha
So I have heard. At one time the Buddha was staying in the land of the Sakyans, where they have a town named Devadaha. Then several mendicants who were heading for the west went up to the Buddha, bowed, sat down to one side, and said to him, “Sir, we wish to go to a western land to take up residence there.”
