大乘義章 10.21

10.21

第一釋名。三聚戒者，謂律儀戒、攝善法戒、攝眾生戒。律儀戒者，亦一名離戒，亦名正受戒。言律儀者，制惡之法說名為律，行依律戒故號律儀。又復內調亦名為律，外應真則目之為儀。防禁名戒，即此律儀離殺等過，故名離戒。正是所愛離過之行，是故亦名正受戒也。攝善戒者，順益名善，要期納善故名曰攝。離不攝過，名攝善戒。攝生戒者，論中亦名利眾生戒。眾多生死名曰眾生，要期攝化故名云攝，離不攝過，名攝眾生戒。以道益物，是故亦名利眾生戒也。此三積聚，故云三聚。名義如是。

First is explaining the names. The three clusters of precepts are: the precept of restraint, the precept of collecting wholesome dharmas, and the precept of collecting sentient beings. The precept of restraint is also called the precept of abandonment, and also called the precept of correct reception. As for 'restraint' (lùyí, saṃvara), the rule that checks evil is called rule (lù, vinaya), and because practice accords with the rule and precepts, it is termed restraint (lùyí). Furthermore, internal harmonization is also called rule, while externally according with the true standard is termed demeanor (yí). Prevention and prohibition are called precepts. This restraint abandons faults such as killing, and is therefore called the precept of abandonment. It is precisely the practice of abandoning faults that is favored, and therefore it is also called the precept of correct reception. As for the precept of collecting wholesome dharmas, conforming with benefit is called wholesome; binding oneself by resolve to embrace the wholesome is therefore called collecting. Being free from the fault of not collecting is called the precept of collecting wholesome dharmas. As for the precept of collecting sentient beings, in treatises it is also called the precept of benefiting sentient beings. Manifold births and deaths are called sentient beings; binding oneself by resolve to collect and transform them is therefore called collecting; being free from the fault of not collecting is called the precept of collecting sentient beings. Benefiting beings with the path is why it is also called the precept of benefiting sentient beings. These three accumulate together, and are therefore called the three clusters. The names and meanings are as such.
