大唐西域記 8.14

8.14

故宮西南有小石山，周巖谷間，數十石室，無憂王為近護等諸阿羅漢，役使鬼神之所建立。傍有故臺，餘基積石；池沼漣漪，清瀾澄鑒，隣國遠人謂之聖水，若有飲濯，罪垢消滅。

To the south-west of the old palace there is a little mountain. In the crags and surrounding valleys there are several tens of stone dwellings which Asoka-raja made for Upagupta and other Arhats, by the intervention of the genii. By the side of it is an old tower, the ruins of which are a mass of heaped-up stones. There is also a pond, the gentle ripples of which play over its surface as pure as a mirror. The people far and near call it the sacred water. If any one drinks thereof or washes in it, the defilement of their sins is washed away and destroyed.
