When inside the monastery, there are five matters: first, one must not carry shoes from behind the latrine up onto the stūpa; second, one must not circumambulate the stūpa in reverse; third, one must not exit the doorways with one's back turned to the Buddha; fourth, one must not spit upon the stūpa; fifth, one must not sit on the wooden railings of the stūpa while walking along them.
