太子瑞應本起經 2.37

2.37

「明日食時，佛持鉢自到迦葉家，受飯而還。於屏處食已，念欲澡漱。天帝知佛意即下，以手指地，水出成池，令佛得用。迦葉晡時，彷徉聚中，見有泉水，怪而問佛：『何緣有此？』佛言：『吾朝得卿飯，於此食已，念欲澡漱，天帝釋指地，令有水出，汝當名此為指地池。』迦葉復念：『是大沙門雖神，故不如我道真也！』

"The next day at mealtime, the Buddha took his bowl, went himself to Kāśyapa's house, received food, and returned. Having eaten in a secluded place, he wished to wash and rinse. Śakra, knowing the Buddha's intention, immediately descended and pointed with his finger at the ground; water welled forth to form a pond so that the Buddha might use it. In the late afternoon, as Kāśyapa was wandering about his settlement, he saw that there was spring water. Puzzled, he asked the Buddha: 'How has this come to be here?' The Buddha said: 'This morning I received your food, and having eaten it here, I wished to wash and rinse. Śakra pointed at the ground, causing water to emerge; you should name this the Finger-Pointed Pond.' Kāśyapa thought again: 'Although this great śramaṇa is spiritual, he is still not equal to my Way, which is real!'
