大唐西域記 9.12

9.12

孤山東北四五里，有小孤山，山壁石室廣袤可坐千餘人矣，如來在昔於此三月說法。石室上有大磐石，帝釋、梵王摩牛頭栴檀塗飾佛身，石上餘香，于今郁烈。

To the north-east of the solitary hill 4 or 5 li there is a small hill, also standing alone. In the side of this hill (has been excavated) a stone chamber. In length and breadth it is enough to seat 1000 persons or so. In this place Tathagata, when living in the world, repeated the law for three months. Above the stone chamber is a great and remarkable rock, on which Sakra, king of Devas, and Brahma-raja pounded some ox-head sandal-wood, and with the dust sprinkled the body of Tathagata. The surface of the stone still emits the scent of the perfume.
