四分律行事鈔資持記 2.863

2.863

《多論》中，初明求作。彼云從三月半至三月盡應作；若得成衣，四月一日應畜（畜，即用也。）；若不成衣，乃至四月半聽求聽作，故云乃至亦爾等。又云：設三月十六日得，一二日即成者，亦得畜用；約準今宗，正犯後戒；部計之異，不可和會；須知求通一月，用限半月，不可濫也。次明畜法，初明本開。長下，明衣量。《四分》長六搩手，則同彼論；廣二磔手半，則廣五尺。以夏下，明開意。既為護衣，故得覆雨，不唯著浴也。此浴下，釋妨。恐謂浴衣那將覆雨，故此釋之。若據今戒，名雨浴衣，謂著雨中浴。是則戒本名兼用局，《多論》名局用通也。《僧祇》不通餘用，與論小異。若著下，以不用正衣，方便免過也。

In the Sarvāstivāda Vinaya Vibhāṣā, it first explains seeking and making. It states that from the middle of the third month to the end of the third month, one should make it; if one succeeds in making the robe, on the first day of the fourth month one should keep it (keeping it means using it); if one does not succeed in making the robe, even up to the middle of the fourth month one is permitted to seek and permitted to make it, hence it says 'even so,' etc. It also states: supposing one obtains it on the sixteenth day of the third month, and finishes it in one or two days, one may also keep and use it; evaluating this by the standard of our current school, this would directly commit the subsequent precept. Differences in sectarian positions cannot be harmonized; one must know that seeking is permitted throughout a whole month, whereas use is restricted to half a month, and they must not be conflated. Next, it explains the method of keeping it; first, it explains the original exception. 'Length' downwards explains the measurements of the robe. In the Dharmaguptaka-vinaya, the length is six spans (diṣṭi), which is the same as that treatise; the width is two and a half spans, which is five chi. 'Because of the summer' downwards explains the intention behind the exception. Since it is for protecting the robes, one may use it to cover oneself from the rain, and not solely wear it for bathing. 'This bathing [robe]' downwards resolves an objection. Fearing one might say, 'How can a bath-robe be taken to cover oneself from rain?', it therefore explains this. If we go by the present precept, it is named 'rain and bath robe', meaning wearing it in the rain to bathe. Thus, the name in the Prātimokṣa-sūtra combines both while its application is narrow, whereas in the Sarvāstivāda Vinaya Vibhāṣā the name is narrow while its application is broad. The Mahāsāṃghika-vinaya does not permit other uses, which differs slightly from the treatise. 'If wearing' downwards refers to not using the standard robes, using an expedient means to avoid an offense.
