又三千威儀云。若不洗大小便比丘。得突吉羅罪亦不得淨僧座具上坐。及禮三寶。設禮無福德。又至舍後上廁。有二十五事。一欲大小便當行時。不得道上為上座作禮。二亦莫受人禮。三往時當直低頭視地。四往當三彈指。五已有人彈指不得逼。六已上正住彈指乃踞身。七正踞中坐。八不得一足前一足却。九不得令身倚。十斂衣不得使垂圊中。十一不得大咽使面赤。十二當直視前不得顧聽。十三不得污壁。十四不得低頭視圊中。十五不得視陰。十六不得以手持陰。十七不得草畫地。十八不得持草畫壁作字。十九用水不得大費。二十不得污湔。二十一用水不得使前手著後手。二十二用土當三過。二十三當用澡豆。二十四得三過用水。二十五設見水草土盡。語直日主者。若自手取為善。

Also, the Sanqian weiyi states: “If a bhikṣu does not wash after urination or defecation, he incurs a duṣkṛta offense, and he also must not sit upon the pure seats of the Saṅgha or pay homage to the Triratna; even if he pays homage, there is no merit. Furthermore, in going behind the lodge to the privy, there are twenty-five matters: First, when walking intending to relieve oneself, one must not pay homage to senior monks on the path. Second, neither should one receive homage from others. Third, when going, one should directly lower the head and look at the ground. Fourth, when approaching, one should snap the fingers three times. Fifth, if someone is already there and snaps their fingers, one must not press close. Sixth, having already stood properly and snapped the fingers, only then does one squat. Seventh, squat properly in the middle. Eighth, one must not have one foot forward and one foot back. Ninth, one must not lean the body. Tenth, gather the robes so they do not hang into the privy pit. Eleventh, one must not strain hard so as to make the face red. Twelfth, one should look straight ahead and not glance around or listen. Thirteenth, one must not soil the walls. Fourteenth, one must not lower the head to look into the privy pit. Fifteenth, one must not look at the genitals. Sixteenth, one must not hold the genitals with the hand. Seventeenth, one must not draw on the ground with grass. Eighteenth, one must not hold grass to write characters on the wall. Nineteenth, in using water, one must not be excessively wasteful. Twentieth, one must not splash and soil. Twenty-first, in using water, one must not let the front hand touch the back hand. Twenty-second, earth should be used three times. Twenty-third, bath beans should be used. Twenty-fourth, water should be used three times. Twenty-fifth, if one sees that the water, grass, or earth is exhausted, speak to the supervisor on duty; if one takes it with one's own hand, that is fine.”
