中天竺舍衛國祇洹寺圖經 2.57

2.57

庫北二院。西是凡僧病人所居，東是病者大小便處。故寺僧院有凡僧病，皆詣此中。

North of the storehouse are two courtyards. The west one is where ordinary sick monks reside, and the east one is where the sick relieve themselves. Therefore, whenever an ordinary monk falls ill in the monastery's saṅgha courtyards, he always goes here.
