There are further five matters: first, when the bhikṣusaṅgha is assembled, one must not enter among the assembly wearing only a tied kāṣāya. Second, one must not stand in the doorway of the lecture hall observing the saṅgha. Third, one must not squat outside the doorway listening to the saṅgha's speech. Fourth, one must not stand in the doorway shouting loudly to detain senior persons. Fifth, if the door of the lecture hall is already closed, one must not push it open; if urgent and wishing to enter, one should snap the fingers three times.
