四分律行事鈔資持記 2.601

2.601

結中。須是己者，簡示他物非所犯故。下引證者，彼約日數以分四衣，大衣為五日衣，七條為四日衣，五條為二日衣，長衣為一日衣。彼恐營衣癈業，故約日限之，則明非他物矣。

In the conclusion: 'It must belong to oneself' differentiates and shows that another's property is not what is violated. Below, citing proof: that text divides the four robes based on the number of days: the great robe is a five-day robe, the seven-strip robe is a four-day robe, the five-strip robe is a two-day robe, and an extra robe is a one-day robe. Fearing that managing robes would cause neglect of practice, it therefore limited them by days, which clearly shows it is not another's property.
