楞伽阿跋多羅寶經註解 4.13

4.13

This discusses the dharmakāya Tathāgata in relation to the virtue of liberation. Saying that "the Tathāgata is spoken of in terms of liberation" means that what the Tathāgata fully reveals is due to realizing that fetters and karma are themselves liberation; thus the Tathāgata and liberation are neither different nor not different. If one says they are different, liberation would be the physical form of the response body and thus impermanent; if one says they are not different, then when a practitioner accords with liberation, there would be no distinction between cause and fruit or person and dharma, yet there is the discrimination of subject and object. Hence the conclusion states: "neither different nor not different."
