四分律行事鈔資持記 2.657

2.657

遇緣中，先引論文。有二緣，小便等是自急緣，加行是他因緣。轉車界者，古記引彼疏云：比丘出界，歸寺數步，明出白佛；佛令於明出處中間安一車，以一杖量伽藍高處；將此杖一頭入車中，一頭出車外，迴轉此車；若杖頭撥及藍牆，又轉及明相出處，不失衣，即離衣開緣。具有多相，故云廣說。次引疏解，初解自緣。病怖畏者，解上等字。又下，解他加行，初敘開。後行人下，牒解。許此難者，解所作憐愍。作謂興此開教也。

Regarding encountering conditions, it first cites the text of the treatise. There are two conditions: urination and the like are pressing conditions of one's own, whereas undertaking an action is an extrinsic condition. Regarding "turning the cart boundary," an ancient record cites their commentary: "A bhikṣu went outside the boundary, and when returning to the monastery a few paces away, dawn broke. He reported this to the Buddha; the Buddha ordered that between the place where dawn broke, a cart be set up, and a staff be used to measure the high point of the saṅghārāma; one end of this staff was placed into the cart, and one end placed outside the cart, and this cart was turned; if the end of the staff reached the wall of the saṅghārāma and also turned to reach the place where the sign of dawn appeared, he did not forfeit the robe," which is an exceptional condition for separation from robes. Because it possesses multiple marks, it says "explained in detail." Next, it cites the commentary's explanation, first explaining one's own conditions. "Sickness and fears" explains the word "and so forth" above. "Also..." below explains other undertakings, first recounting the exception. Afterwards, "the traveler..." repeats and explains. "Permitting these difficulties" explains "acting out of compassion." "Acting" refers to establishing this exceptional teaching.
