Vairochana means "He Who Is Like the Sun" or "the Radiating One." Vairochana regarded as origin of the five Dhyani Buddha. His wisdom is the Wisdom of the Dharmadhatu. The Dharmadhatu ( Meaning Of DHARMADHATU ) is the Realm of Truth, in which all things exist as they really are. Vairochana's wisdom is also referred to as the All-Pervading Wisdom of the Dharmakaya. The Dharmakaya is the Body of the Law, or the absolute Buddha nature.
Vairochana's transcendent wisdom reveals the realm of highest reality and overcomes the poison of ignorance, or delusion. His wisdom is considered to be the origin of all the wisdoms of the Dhyani Buddhas.
Vairochana is usually located in the center of the stupa or mandalas of the Dhyani Buddhas. Sometimes he is placed between Akshobhya and Ratna Sambhava in the stupa. He resides always in the Akanistha heaven. According to some texts, he is positioned in the east. His color is white (or blue), symbolizing a pure consciousness. He rules over the element of ether and embodies the skandha of consciousness. In some systems, he is associated with the skandha of form.
His symbol is the dharmachakra, the wheel of the Teaching, or the wheel of the Law. It denotes the teaching of the Buddha. Its eight spokes represent the Noble Eightfold Path, which Gautama revealed in his first sermon after his enlightenment. This symbol is printed around the border of the lithograph. Vairochana's lotus throne is supported by the lion, symbol of courage, boldness and an eager, advancing spirit.
Vairochana's mudra is the dharmachakra (Bodhyanga) mudra, the gesture of turning the wheel of the Teaching. His vehicle is a pair of lions symbolizing lions roar of dharmadhatujnana which terrifies
all wrong views. He can be recognized through white disc or dharmacakra which cuts all wrong views.Because he embodies the wisdom of all Buddhas, Vairocana Buddha originates from the seed syllable Om.
His mantra is "Om Vairochana Om."
In some esoteric sect of Japan he is said to be the supreme lord of secret vehicle i.e. Mahavairocana.
