《太平广记·卷三百九十六·雨（风》
不空每次祈雨时，没有其他规则，只是摆几个漂亮的座位，用手旋转数寸长的木制神像，念着咒语把神像抛起来，它就会自行站立在座位上。
每祈雨，无他轨则，但设数绣座，手旋数寸木神，念咒掷之，自立于座上。
Every time Bukong prayed for rain, there were no other rules. He just set up a few nice seats, turned a few inches long wooden idol with his hand, recited a mantra and threw it up, then it would stand on the seat by itself.
