Answer: This teaching of the three natures is spoken with hidden intention by the buddhas; it is the place where the various consciousnesses arise, the source and origin of the doctrinal net. If one approaches and grasps them, one falls into ordinary, worldly views; if one leaves and abandons them, one loses the gateway of noble wisdom.

Therefore Master Zang [Fazang], relying on the Huayan school, explained the meaning of identity and difference of the three natures:
First, the consummate tathatā has two meanings: (1) unchanging, and (2) according with conditions.
Second, the other-dependent has two meanings: (1) seeming existence, and (2) lack of nature.
Third, the imagined grasping has two meanings: (1) existence in deluded sentiment, and (2) non-existence in principle.

By virtue of tathatā being unchanging, the other-dependent having no nature, and the grasped being non-existent in principle, through these three meanings, the three natures are of one single limit. Furthermore, in terms of tathatā according with conditions, the other-dependent having seeming existence, and the grasped existing in deluded sentiment, through these three meanings, they are also not different.

Therefore, the real covers the false, seeking the branch penetrates the source of reality, and nature and characteristics blend and penetrate, without hindrance or obstruction.
