四分律行事鈔資持記 3.55

3.55

三明受持，對首中，用法分二，前示《四分》缺文，初句立制。若下，明再受。疑謂先受後忘，或復失否未了，並令捨已更受明白。昔下，次明古今用別，初引古。注顯不同之相。彼律約夜分三，內宿初夜成犯；覆罪護夏，約明相犯；離衣犯雖明相，持通夜分。準《戒疏》四句簡之，一明去暗還（日未沒去，夜分還界，諸律不犯。），二暗去明還（《僧祇》不犯，通夜會故；《四分、十誦》成犯，隔明相故。），三明去明還（日未沒去，隔明方還，諸部同犯。《僧祇》唯此一句犯。），四暗去暗還（諸部非犯）。次明今用。注示取意，見上次句。

Under the third [heading], "Explaining the Reception and Maintenance [of Robes], Facing a Counterpart": the application of the method is divided into two parts. The former indicates the missing text in the Dharmaguptaka-vinaya; the initial sentence establishes the prohibition. "If... below" explains receiving them again. "Doubt" means having previously received them and later forgotten, or being unclear as to whether one has lost them or not; in all such cases, one is ordered to relinquish them and then receive them anew so that it is clear. "Formerly... below" next explains the difference in usage between ancient and modern times; it first cites the ancients. The note reveals the marks of their differences. That Vinaya divides the night into three watches: sleeping within [the boundary] constitutes an offense during the first watch; concealing offenses and guarding the summer retreat incur offenses based on the morning dawn; and though the offense of separation from the robes depends on the morning dawn, maintaining them extends throughout the night. According to the Precept Commentary, one analyzes this with four propositions: (1) Departing in the light and returning in the dark. (Departing before sunset and returning to the boundary during the night: across all Vinayas, this is not an offense.) (2) Departing in the dark and returning in the light. (In the Mahāsāṃghika-vinaya this is not an offense, because it accommodates the whole night; in the Dharmaguptaka-vinaya and the Daśādhyāya-vinaya it constitutes an offense, because the morning dawn has intervened.) (3) Departing in the light and returning in the light. (Departing before sunset and returning only after the dawn has intervened: all schools concur that this is an offense. In the Mahāsāṃghika-vinaya, an offense is incurred only in this single proposition.) (4) Departing in the dark and returning in the dark. (Across all schools, this is not an offense.) Next, it explains present-day usage. The note indicates the underlying intention, which can be seen in the second phrase above.
