梁法雲講次天華散墜。又唐西京勝光寺道宗講時天華施遶講堂飛流戶內。但不委地。久之還無。

While Fayun of the Liang was lecturing, heavenly flowers scattered and fell. Also, when Daozong of Shengguang Monastery in the Western Capital during the Tang was lecturing, heavenly flowers circled around the lecture hall and flew into the room, but they never touched the ground, and after a long time they vanished into nothingness.
