大唐西域記 9.22

9.22

精舍東北石㵎中有大磐石，是如來曬袈裟之處，衣文明徹，皎如彫刻。其傍石上有佛脚迹，輪文雖暗，規摸可察。北山頂有窣堵波，是如來望摩揭陀城，於此七日說法。

By the side of the vihara there are several stone houses, where Sariputra and other great Arhats entered Samadhi. In front of the stone house of Sariputra is a great well, dry and waterless. The hollow (shaft) still remains. To the north-east of the vihara, in the middle of a rocky stream, is a large and flat stone. Here Tathagata dried his Kashaya garment. The traces of the tissue of the robe still remain, as though they were cut out on the rock. By the side of this, and upon a rock, is a foot-trace of Buddha. Although the "wheel" outline is somewhat obscure, yet it can be distinctly traced. On the top of the northern mountain is a stupa. From this point Tathagata beheld the town of Magadha, and for seven days explained the law. To the west of the north gate of the mountain city is the mountain called Pi-pu-lo (Vipula-giri). According to the common report of the country it is said, "On the northern side of the south-western crags of this mountain there were formerly five hundred warm springs; now there are only some ten or so; but some of these are warm and others cold, but none of them hot." These springs have their origin to the south of the Snowy Mountains from the Anavatapta (Wu-jeh-no-c'hi) lake, and flowing underground, burst forth here. The water is very sweet and pure, and the taste is like that of the water of the lake.
