大乘義章 1.76

1.76

問曰：若爾，與彼前後緣成何別？釋云：一體隨義分異，分取攬別成總義邊，說為緣成；分取前後相續義邊，說為相續。又更分別，亦有少異。異相如何？緣成則寬，相續則狹。如續緣成中，攬十二時合成一日，十二時中寅申相對、卯酉相生，時雖隔絕不相接續，而得和合共成一日，故說為寬。相續假中，雖復宣說十二時分續成一日，於中寅申卯酉相對，時中隔絕，不得說為相續成目，唯相隣者得說為續，故名為狹。體相如是（此二門竟）。

Question: If so, what is the difference between this and before-and-after condition-dependent constitution? Explanation: It is a single entity differentiated according to meaning. Taking the aspect of gathering particulars to constitute a composite, it is called condition-dependent constitution; taking the aspect of succession before and after, it is called continuity. Furthermore, in distinguishing them further, there is also a slight difference. What is the difference? Condition-dependent constitution is broad, while continuity is narrow. For instance, in the condition-dependent constitution of continuity, gathering twelve temporal hours constitutes one day; among the twelve hours, yin and shen correspond, and mao and you produce each other—though separated in time and not contiguous, they are able to harmonize and together constitute one day; therefore it is said to be broad. In the provisionality of continuity, although one also speaks of twelve temporal segments continuing to constitute one day, among them yin and shen, mao and you correspond across intervals of time and cannot be said to continue to constitute a day; only those that are adjacent can be said to continue; therefore it is called narrow. Such are their essential characteristics. (These two gates are concluded.)
