Vairochana is one of the Dhyani Buddhas
and his name means 'He Who Is Like the Sun' or 'the Radiant One.' Representing the integration of or the origin of the Dhyani Buddhas, Vairochana's wisdom is said to be the Wisdom of the Dharmadhatu ( the Realm of Truth, in which all things exist as they really are), as well as the all-pervading Wisdom of the Dharmakaya. Dharmakaya stands for the absolute Buddha nature. So Vairochana's wisdom is said to be the sum total of the wisdom of all the Dhyani Buddhas.
Meditating on Vairochana is a strong antidote to the poison of ignorance, or delusion. Vairochana is usually located in the center of the mandalas of the Dhyani Buddhas. However some texts refer to him as positioned in the east. His color is white (or blue), symbolizing pure consciousness. He is master of the element of ether and embodies the skandha of consciousness. In some systems, he is seen associated with the skandha of form.
Vairochana's symbol is the dharmachakra, the wheel of the Buddhist Law. The eight spokes of his Dharmachakra represent the noble eightfold path of Buddhism. Vairochana's lotus throne is supported by the lion, the symbol of courage and an eager, advancing spirit. Vairochana's mudra is the dharmachakra mudra, the gesture of turning the wheel of the Teaching, his bija is the universal sound Om and his mantra is 'Om Vairochana Om'.
