What is "vairocana"

Vairocana (also Vairochana or Mahāvairocana, ) is a celestial buddha who is often interpreted, in texts like the Flower Garland Sutra, as the Dharma Body of the historical Buddha ( Siddhartha Gautama). In Chinese, Korean, and Japanese Buddhism, Vairocana is also seen as the embodiment of the Buddhist concept of Emptiness. In the conception of the Five Wisdom Buddhas of Mahayana and Vajrayana Buddhism, Vairocana is at the centre and is considered a Primordial Buddha.

Vairocana is not to be confused with Vairocana Mahabali, son of Virochana.
