大比丘三千威儀 1.29

1.29

When rising from sleep and wishing to go out the door, there are five matters: first, when rising and getting down from the bed, one must not cause the bed to make a sound; second, when putting on shoes, one must first shake them out; third, standing upright, one puts on the Dharma robes; fourth, when about to open the door, one first snaps the fingers three times and must not cause the door to make a sound; fifth, if there is a Buddha image inside the room, one must not turn one's back to it when exiting, but should face back toward the room to exit, and upon exiting, one must not stand still and converse with people.
