《太平广记·卷四百二十一·龙四》
三藏不得已，就让他的徒弟取来近一尺长的一块桦树皮，在上面承接着一条小龙，把炉火、盆和香水放到前边，三藏转入念咒，大声祷告。
三藏不获已，乃命其徒，取华木皮仅尺余，缵小龙于其上，而以炉瓯香水置于前。三藏转咒，震舌呼祝。
Sanzang had no choice, so he let his disciple fetch a piece of birch bark about a foot long, put a small dragon on it, and put the stove, basin, and perfume in front. Sanzang began chanting and praying loudly.
