大般涅槃經義記 7.53

7.53

"How is it that the arising of non-arising cannot be spoken of?" cites the question regarding the third. "Arising is indeed termed arising" uses the prior to refute the subsequent. It is precisely because what arises is immediately termed arising that it is not definitively non-arising. "Arising does not arise of itself" uses the subsequent to refute the prior. The aforementioned mark of arising can only produce others, and is thus called arising; its own essence does not arise. Since its essence does not arise, it is called non-arising. Because it does not arise, it cannot be definitively spoken of as arising. "Cannot be spoken of" means that because both arising and non-arising are non-definitive, they cannot be spoken of.
