Vairochana Buddha Talks

Vairocana ("The Sun", "Solar" or "Shining" in Sanskrit), also known as Mahāvairocana (Great Sun), is a major Buddha from Mahayana and Vajrayana Buddhism. He is often compared to the Sun, because both bestow their light impartially upon all beings. However, unlike the Sun, whose light can be blocked, and which disappears at night, Vairocana's light is omnipresent, impossible to block, and shines eternally. Hence, he is called the "Great Sun". In East Asian Buddhism, Vairocana is called 大日如來code: zho promoted to code: zh (lit. 'Great Sun Thus Come One') or 毘盧遮那佛code: zho promoted to code: zh (lit. 'Vairocana Buddha').

In Mahayana and Vajrayana Buddhism, Vairocana is the Dharmakāya (lit. 'Dharma-body') of all Buddhas (the Dharma-body is the "true body" of all Buddhas, equivalent to the Ultimate Reality), which is formless, omnipresent, self-existent, eternal, indestructible, unable to be defiled, and is the source of all manifestations. The historical Gautama Buddha is one of the emanation bodies of Vairocana Buddha.
