“I allow half walls.” People looked over the half walls. “I allow three kinds of rooms: rectangular rooms, long rooms, and upper rooms.” On one occasion the monks made a room in the middle of a small dwelling. There was no access around the room. “In a small dwelling you should make the room on the side, but in a large dwelling in the middle.” At that time the base of the wall of a certain dwelling was deteriorating. “I allow timber supports.” It rained through the wall.
