佛遺教經論疏節要 1.44

1.44

〔補註〕不盡滅法者，佛滅則法滅，以有戒存則法不盡滅。有此不盡滅之戒法，是如來法身常度眾生也。

[Supplementary note:] As for "the Dharma that does not become utterly extinct": when the Buddha passes into extinction, the Dharma is extinguished; yet because the precepts remain, the Dharma is not utterly extinguished. Having this unextinguished Dharma of precepts is the Tathāgata's dharmakāya constantly delivering sentient beings.
