四分律行事鈔資持記 1.75

次科，上二句敘分宗。《義鈔》云：毱多受法既少，不能均融，故分五部；然既大聖懸記，蓋是時機所宜；執諍雖殊，無非證道；即《大集》云：五部雖異，不妨諸佛法界涅槃是也。下二句明各集。競謂爭馳。言大眾者，此濫窟外部。

In the next section, the first two lines recount the division of schools. The Meaning Manual says: "Because [Upagupta] received few dharmas and could not harmonize them evenly, it divided into five schools. Yet since the Great Sage prophesied it long before, it was simply appropriate to the capacities of the time. Although their attachments and disputes differed, none failed to realize the path; this is precisely what the Mahāsaṃnipāta says: 'Although the five schools differ, they do not obstruct the dharmadhātu and nirvāṇa of the Buddhas.'" The lower two lines clarify their respective compilations. "Competing" means contending and racing. The mention of "the Great Assembly" here risks confusion with the school outside the cave.
