大唐西域記 1.115

頂骨伽藍西南有舊王妃伽藍，中有金銅窣堵波，高百餘尺。聞諸土俗曰：其窣堵波中有佛舍利升餘，每月十五日，其夜便放圓光，燭燿露盤，聯暉達曙，其光漸斂，入窣堵波。

To the south-east of this convent there is another, which is also called the convent of the old king; in this is a piece of the skull-bone of Tathagata; the surface of it is about an inch in breadth, its colour a yellowish white; the little hair orifices are plainly seen. There is, moreover, a hair-top of Tathagata of a dark auburn colour; the hair turns to the right; drawing it out, it is about a foot long; when folded up it is only about half an inch. These three objects are reverenced with offerings by the king and the great ministers on each of the six fast (holy) days. To the south-west of the convent of the skull-bone is the convent of the wife of the old king, in which there is a gilded stupa (copper gilt), about 100 feet in height. Tradition says in this stupa is about a pint of the relics of Buddha. On the fifteenth day of each month, in the evening, it reflects a circular halo of glory which lights up the dew-dish. Thus it shines till the morning, when it gradually disappears and enters the stupa.
