大唐西域記 5.45

5.45

城西南八九里，毒龍石窟。昔者如來伏此毒龍，於中留影，雖則傳記，今無所見。其側有窣堵波，無憂王之所建也，高二百餘尺。傍有如來經行遺迹及髮、爪窣堵波，病苦之徒，求願多愈。釋迦法盡，此國最後，故上自君王，下及眾庶，入此國境，自然感傷，莫不飲泣，悲歎而歸。

To the south-west of the city 8 or 9 li is a stone dwelling of a venomous Naga. Having subdued this dragon, Tathagata left here his shadow; but though this is a tradition of the place, there is no vestige of the shadow visible. By the side of it is a stupa built by Asoka-raja, about 200 feet high. Near this are marks where Tathagata walked to and fro, and also a hair and nail stupa. The disciples who are afflicted with disease, by praying here mostly are cured. The law of Sakya becoming extinct, this will be the very last country in which it will survive; therefore from the highest to the lowest all who enter the borders of this country are deeply affected, even to tears, ere they return. To the north-east of the Naga dwelling in a forest, after going about 700 li, through which we cross the Ganges, going northward we arrive at the town of Kasapura. This town is about 10 li in circuit; the inhabitants are rich and well-to-do (happy). By the side of the city is an old sangharama, of which the foundation walls alone exist. This was where Dharmapala refuted the heretics.
