Dharmakāya

A Buddha is said to possess three bodies: dharmakaya, sambhogakaya, and nirmanakaya.
The dharmakaya, often translated as the “body of truth,” refers to the absolute nature of a buddha, which all buddhas share and which is identical to the absolute nature of all that exists: emptiness. The dharmakaya is non-dual, devoid of conceptuality and free from all characteristics. (See also sambhogakaya and nirmanakaya).
