起信論疏筆削記 8.12

8.12

論　非一異中，三：初、約法略明。疏　真如者，即前不生滅也。非少分動，故云全體。既全體動成生滅法，何異之有？雖成生滅而性不變，從本便爾，非適今也，故云而恒。生滅是變，與不變義別，故云非一。

Regarding 'neither one nor different' in the treatise, there are three parts: first, briefly clarifying it with regard to the dharma. The Commentary states: 'Tathatā' is the preceding non-arising and non-ceasing. Because it is not a partial movement, it says 'in its entirety'. Since it moves in its entirety to become the dharmas of arising and ceasing, what difference could there be? Although it becomes arising and ceasing, its nature does not change; it has been so from the origin, not just beginning now, hence it says 'and yet constant'. Arising and ceasing is change, which differs in meaning from unchanging, hence it says 'neither one'.
