有道士造老像。二菩薩侍之。一曰金剛藏。二曰觀世音。又道士服黃布帔。或似服帊通身被之。偷佛僧袈裟法服之相。其服黃帔。乃是古賢之衣。橫被加前兩帶者。今悉削除。學僧服像。

There are Daoists who make images of Laozi with two bodhisattvas attending him: one is called Vajragarbha, and the other is called Avalokiteśvara. Furthermore, Daoists wear yellow cloth capes, or wear something like a cloak covering the entire body, stealing the appearance of Buddhist monks' kāṣāya robes. Their wearing of yellow capes was originally the clothing of ancient worthies, draped crosswise with two ribbons added in front; today, all of these have been eliminated to imitate the appearance of Buddhist monastic robes.
