四分律行事鈔資持記 1.1112

1.1112

推究中，初句徵。《五分》下，釋；初引《五分》制法。有比丘者，即緣起也。乃下，立制。往彼處者，明親附也。若房下，明遙依也。若已下，明往返遇緣隨結成者；請法因緣，非心慢故，準下還成前安。次引《四分》制犯。罪相階降，在文可知。

In investigating: the first sentence questions. Under 'the Mahīśāsaka...', it explains: first citing the Mahīśāsaka-vinaya's regulated procedure. 'There was a bhikṣu' is the origin story. Under 'then...', it establishes the regulation. 'Going to that place' clarifies relying closely in person. Under 'if rooms...', it clarifies relying from afar. Under 'if already...', it clarifies that when encountering circumstances during travel, the retreat is established accordingly; because the cause and condition was seeking the Dharma and not negligence of mind, according to the below it still constitutes the earlier rains retreat. Next, the Dharmaguptaka-vinaya is cited to regulate offenses. The gradations of the marks of offenses can be known from the text.
