往小便文言可云私（左傳師惠過宋朝將私焉。注云。小便也。律云小行）毘尼母云。不聽於伽藍內處處小便。當聚一屏猥處。若瓦瓶木桶埋地中。以物蓋覆。勿令有臭氣。五分云。許將小便器入房中。密塞口房外應滿盛水○優鉢祇王經云。伽藍法界內地漫（去聲亂也）大小便。五百生墮拔波地獄。後二十劫。常遣肘手。把此穢地。

To go to urinate may be expressed in literary terms as si (in the Zuo zhuan: 'Master Hui passed the court of Song and was about to si.' The commentary states: 'It means to urinate. The Vinaya calls it "minor evacuation"'). The Vinayamātṛkā states: 'One is not permitted to urinate everywhere within the monastery. One should designate a single secluded and screened place, burying an earthenware jar or wooden tub in the ground and covering it with an object so that there is no foul odor.' The Mahīśāsaka says: 'It is permitted to bring a chamber pot into the room, tightly stopping its mouth; outside the room, there should be a full vessel of water.' The Upātikā-rāja-sūtra states: 'If one urinates or defecates recklessly within the monastery's Dharma boundary ground, for five hundred lifetimes one will fall into the Bāpa Hell. Thereafter, for twenty kalpas, one will constantly have one's hands and forearms made to grasp this foul soil.'
