大般涅槃經集解 62.32

62.32

案僧亮曰：第九歎經。佛及菩薩功德智慧，經實其本，故讚歎也。僧宗曰：上言人由經益，則經有資成人義，故次歎也。寶亮曰：海有八德，以譬經也。一者因眾生之福，海則漸深。眾生有感，所以經教次第從淺至深也。二逐風而行，諸佛菩薩隨緣而化也。三河水入者，明涅槃納眾命之器也。下去類爾也。

Sengliang notes: The ninth section praises the sūtra. The merits and wisdom of the buddhas and bodhisattvas truly have their root in the sūtra; therefore it is praised. Sengzong says: Above it said that persons are benefited through the sūtra, which means that the sūtra possesses the quality of assisting and bringing people to completion; hence it is praised next. Baoliang says: The ocean has eight virtues to serve as a metaphor for the sūtra. First, due to the merits of sentient beings, the ocean gradually deepens. Sentient beings have resonance [with the teaching]; therefore the instructions of the sūtra proceed in order from shallow to deep. Second, it moves according to the wind: the buddhas and bodhisattvas transform [sentient beings] according to conditions. Third, rivers entering it: this explains that nirvāṇa is a vessel that takes in all lives. From here downward, the rest are analogous.
