《资治通鉴·汉纪·汉纪十二》
人们见不到神灵，只能听到神灵的声音，同人的声音一样。神灵忽来忽去，来时肃然有风，居于帷帐之中。
神君非可得见，闻其言，言与人音等，时去时来，来则风肃然，居室帷中。
People could not see the deities, but could only hear their voices, which sounded like human voices. The deities came and went suddenly, with a sudden gust of wind when they arrived, and resided in the curtain.
