15.77

「不說犯重人至制立如是」者，經部答。不說一切諸犯重人皆成波羅夷罪，但成波羅夷罪，由覆藏故，定說非苾芻。謂或有人相續身中有殊勝慚愧，雖復犯重，非他勝罪，由彼無有一念覆心，如禪難提等。法主世尊制立如是。

"It is not said of a person who has committed a grave offense ... established [the rule] in this way": The Sautrāntika answers. It is not said that all persons who have committed a grave offense incur a pārājika offense; rather, it is only when one incurs a pārājika offense on account of concealment that he is definitely said not to be a bhikṣu. That is to say, there may be someone within whose mental continuum there is exceptional shame and conscience: although he has committed a grave offense, it is not an offense of defeat (pārājika), because he did not have even a single thought of concealment, as in the case of Chandaka and others. The Lord of the Dharma, the World-Honoured One, established [the rule] in this way.
