大唐西域記 3.27

3.27

城北十二三里有窣堵波，無憂王之建也。或至齋日，時放光明，神花天樂，頗有見聞。聞諸先志曰：近有婦人，身嬰惡癩，竊至窣堵波，責躬禮懺，見其庭宇有諸糞穢，掬除灑掃，塗香散華，採青蓮。重布其地。惡疾除愈，形貌增妍，身出名香，青蓮同馥。斯勝地也，是如來在昔修菩薩行，為大國王，號戰達羅鉢剌婆（唐言月光），志求菩提，斷頭惠施。若此之捨，凡歷千生。

To the north of the city 12 or 13 li is a stūpa built by Aśōka-rāja. On feast-days (religious commemoration days) it glows with light, and divine flowers fall around it, and heavenly music is heard. According to tradition, we find in late times there was a woman whose body was grievously afflicted with leprosy. Coming to the stūpa secretly, she offered worship in excess and confessed her faults. Then seeing that the vestibule (the open court in front of the stūpa) was full of dung and dirt, she removed it, and set to work to sweep and water it and to scatter flowers and perfumes; and having gathered some blue lotus flowers, she covered the ground with them. On this her evil leprosy left her, and her form became lovely, and her beauty doubled, whilst from her person there came the famed scent of the blue lotus, and this also is the reason of the fragrance of this excellent place. This is the spot where Tathāgata formerly dwelt when he was practising the discipline of a Bodhisattva; he was then the king of a great country and was called Chen-ta-lo-po-la-po (Chandraprabha); he cut off his head, earnestly seeking the acquirement of Bodhi: and this he did during a thousand successive births, (for the same object and in the same place).
