大方廣佛華嚴經隨疏演義鈔 6.29

6.29

疏「若云第二時中」下破第二時。於中三：一破說空、二破不明常住、三結立正義。初中又二：第一引制戒，明十二年後說有。故戒經云「善護於口言，自淨其志意，身莫作諸惡，此三業道淨。能得如是行，是大仙人道。此是釋迦如來於十二年中，為無事僧說是戒經。從是已後，廣分別說。」明知十二年後，始制廣戒，廣戒即是明有。

Regarding the commentary's "If one says that in the second period..." onward, this refutes the second period. Within this there are three parts: first, refuting the claim that it expounded only emptiness; second, refuting the claim that it did not reveal eternal abiding; and third, concluding by establishing the correct meaning. In the first part, there are again two: first, citing the institution of precepts to show that existence was taught after the twelve years. Thus the Vinaya sūtra says: "Guard well the speech of your mouth, / Purify your own mind's intention, / Do not commit evils with the body; / Pure are the paths of these three karmas. / To be able to attain such practice / Is the path of the Great Sage. / This is the Prātimokṣa sūtra that Śākyamuni Tathāgata expounded during the twelve years for the monks who were free of infractions. From this time onward, it was extensively differentiated and expounded." This makes it clear that only after the twelve years were the extensive precepts instituted, and the extensive precepts are precisely the elucidation of existence.
