In Buddhism, one of three “bodies” of the Buddha. It is defined as the Body (“kaya”) of Law (“Dharma”), the Body of First Cause or the Body of Essence, which is one with Absolute Reality.
The Dharmakaya corresponds to the upper figure in the Chart of Your Divine Self, the causal body, including the I AM Presence. It is the he third of the three bodies of the Buddha (trikaya); the ultimate body from which the other two emanate for the purpose of interacting with and assisting life; the 'essence-being' of all Buddhas, immutable and undifferentiated, identical with absolute knowledge or reality.
