楞伽阿跋多羅寶經註解 4.86

4.86

常與無常之名無異外道，不以義定，邪正曷分？上明不生不滅是真常之義，已破外計，未辯無常邪正之殊，所以再請決也。問辭可見。

The names "permanence" and "impermanence" are no different from those used by tīrthikas; if not determined by their meaning, how could deviant and correct be distinguished? Above, it was explained that non-origination and non-cessation is the meaning of true permanence, which already refuted external reckonings; yet the difference between deviant and correct impermanence had not been distinguished, which is why he inquires again for a resolution. The phrasing of the question is evident.
