金光明經文句記 2.42

2.42

Third, the precept against sexual misconduct, in two parts: first, demonstrating the observance and violation in terms of phenomena and principle. Demonstrating phenomena and principle has the intention of observing both together, using phenomena to support principle and using principle to guide phenomena. Since we live in the final age, efficacy lies in phenomenal observance; this is the meaning of the Nirvāṇa Sūtra's supporting the Vinaya. When the observance of principle discusses being stained and unstained: the mind contemplating another realm is called stained phenomena; when the realm itself serves as contemplation, only then is it called unstained. Speaking of "various kinds": phenomena follow the contemplation of principle, and the lesser, greater, biased, and complete are fully differentiated below.
