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。七正踞中。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。十七不得草蓋地。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。二十四三過用水。二十五設見水草土。盡當語直日主者。若自手取為善。

Furthermore, the Three Thousand Dignified Manners says: "If one does not wash after defecating or urinating, a monk incurs a duṣkṛta offense, and is also not permitted to sit upon the pure seating mats of the Saṃgha or prostrate to the Three Jewels; even if one prostrates, there is no merit. Furthermore, in going behind the lodge to use the privy, there are twenty-five matters: 1. When walking with the desire to defecate or urinate, one must not pay homage to a senior monk on the road. 2. Neither should one accept homage from others. 3. When going, one should keep the head bowed straight and look at the ground. 4. Upon arrival, one should snap the fingers three times. 5. If someone has already snapped their fingers [inside], one must not press forward. 6. Having entered and stood properly, one snaps the fingers before squatting. 7. One squats squarely in the middle. 8. One must not have one foot forward and one foot back. 9. One must not lean the body. 10. Gather the robes so as not to let them hang down into the privy. 11. One must not strain heavily so as to make the face red. 12. One should look straight ahead and not look around or listen. 13. One must not soil the walls. 14. One must not lower the head to look into the privy. 15. One must not look at the genitals. 16. One must not hold the genitals with the hand. 17. One must not cover the ground with grass. 18. One must not take grass to draw or write characters on the wall. 19. In using water, one must not be overly wasteful. 20. One must not soil or splash. 21. In using water, one must not let the front hand touch the back hand. 22. In using earth, one should do so three times. 23. One should use bath beans. 24. Three times one should use water. 25. If one sees that the water, grass, or earth is exhausted, one should tell the officer on duty; taking it with one's own hand is even better."
