2.113

言知下，若說有知，但欲令人通曉其鑒照之用，豈有知相可取？不知下，若說無知，但欲令人知無惑取之相，豈謂一向無知？

From "speaking of knowing..." onward: if one speaks of possessing knowing, it is merely to make people understand its function of mirror-like illumination; how could there be a mark of knowing to be grasped? From "not knowing..." onward: if one speaks of being without knowing, it is merely to make people realize the absence of the mark of grasping in delusion; how could it mean being completely without knowing?
