大唐西域記 3.13

3.13

珊尼羅闍川北石崖邊，有窣堵波。病者至求，多蒙除差。如來在昔為孔雀王，與其群而至此，熱渴所逼，求水不獲，孔雀王以𭪿啄崖，涌泉流注。今遂為池，飲沐愈疾。石上猶有孔雀蹤迹。

To the north of the valley Shan-ni-lo-shi, by the side of a steep rock, is a stupa. Of those who, being sick, have come there to seek (restoration), most have recovered. In old time Tathagata was the king of peacocks; on one occasion he came to this place with his followers. Being afflicted with tormenting thirst, they sought for water on every side without success. The king of the peacocks with his beak struck the rock, and forthwith there flowed out an abundant stream which now forms a lake. Those who are afflicted on tasting or washing in the water are healed. On the rock are still seen the traces of the peacock's feet.
