四分律行事鈔資持記 2.919

2.919

《僧祇》三開，初開別戶。即同別室。若佛下，次開遇緣。施障隔斷，事同異處。注示施障，須成兩室，各不相通，方免斯過。一頭著內壁，一頭出門簷，故云相當。當，猶抵也。末句遮濫。若無下，三明互相臥起，方便離過。言無福者，令僧犯戒故。注中以互坐臥合犯屏坐，故準《五分》有伴通之。

The Mahāsāṃghika-vinaya has three exceptions: first, it permits a separate door, which is identical to a separate room. Below "if the Buddha," second, it permits encountering circumstances: setting up a barrier to partition it off makes the matter equivalent to different places. The note indicates that setting up a barrier must create two rooms that do not communicate with each other before one can avoid this fault. One end touches the inner wall, and one end extends beyond the door eaves; hence it says "corresponding." "Dang" is like reaching to. The final sentence prevents abuse. Below "if there is no," third, it clarifies mutually lying down and getting up as an expedient to avoid the fault. Saying "without merit" is because it causes the monk to violate the precept. In the note, because mutually sitting and lying down would properly violate sitting in a secluded place, it resolves this by according with the Mahīśāsaka-vinaya on having a companion.
