法華義疏 11.197

11.197

「爾時一切」下，第二，明佛滅後供養。又開三別：第一、喜見發問，開涅槃之端。「爾時日月」，第二、如來滅度。「涅槃時到」者，謂安住三德為入涅槃也。「滅盡時至」者，捨應歸真也。

From "At that time, Sarvasattva..." down is the second: explaining offerings after the Buddha's parinirvāṇa. This further opens into three distinctions: first, Sarvasattvapriyadarśana raises a question, opening the occasion of nirvāṇa. "At that time, Candrasūryavimalaprabhāsaśrī..." is the second: the Tathāgata passes into cessation. "The time for nirvāṇa has arrived" refers to abiding peacefully in the three virtues as entering nirvāṇa. "The time of extinction has arrived" refers to relinquishing the response [body] and returning to the true.
