大般涅槃經義記 1.8

1.8

As for parinirvāṇa, pari is translated here as 'entry.' The meaning of entry is threefold: First, discussing it in terms of reality, to bring delusions to rest and return to the real, proceeding from cause toward fruit, is called entry. Second, discerning entry based on transformation, manifesting extinction has its causes, manifesting the cessation of body and wisdom and proceeding to enter the unconditioned. Third, speaking of entry in terms of the contrast between the real and the manifest, to bring transformation to rest and return to the real. What is discussed here is fully endowed with these three meanings.
