大般涅槃經集解 18.91

18.91

Sengliang states: This illustrates the Buddha. Because he has transcended the three realms, he is an 'unusual person'. Sengzong states: The Buddha. He takes the distinct difference between cause and fruit as an analogy. Tan'ai states: Having already illustrated having it yet not seeing it, from this point downward illustrates why it could not be expounded immediately.
