太子瑞應本起經 2.39

2.39

「迦葉見池邊有兩好石，又問：『何緣有此？』佛言：『吾欲浣濯及欲曬衣，天帝到頞那山上取此石來。』迦葉復念：『是大沙門雖神，故不如我道真也！』

"Seeing two fine stones beside the pond, Kāśyapa asked again: 'How have these come to be here?' The Buddha said: 'I wished to wash and dry my robe, and Śakra went to Mount *Ana and brought these stones.' Kāśyapa thought again: 'Although this great śramaṇa is spiritual, he is still not equal to my Way, which is real!'
