大般涅槃經集解 47.8

47.8

案僧亮曰：第二難闡提不應成佛。何者？四人是邪定。若邪定不定，正定亦應不定。若不定者，涅槃則非常。若有常樂，則闡提不應成佛也。寶亮曰：此下作不定難。且前并列不定之事，然後結難。若闡提不定，後還成佛者，萬法皆然。涅槃既是萬法之數，亦應不定，還可作生死。法瑤曰：若更是不定，當知無有常樂也。

Sengliang comments: The second challenge is that the icchantika should not attain buddhahood. Why? The four kinds of persons are wrongly determined. If the wrongly determined are indeterminate, the rightly determined should also be indeterminate. If indeterminate, nirvāṇa is then not eternal. If there are permanence and bliss, then the icchantika should not attain buddhahood. Baoliang says: Below this, he poses the challenge of indeterminacy. Moreover, he first enumerates instances of indeterminacy and then concludes the challenge. If the icchantika is indeterminate and later reverts to attaining buddhahood, all phenomena are likewise. Since nirvāṇa is counted among all phenomena, it should also be indeterminate and could revert to being saṃsāra. Fayao says: If it is further indeterminate, one should know that there is no permanence and bliss.
