Vairocana is one of the Five Dhyani Buddhas created by Adhi Buddha. In Sanskrit, the name vairocana means "luminous" or "embodiment of light". He is also referred to as the "great illuminating one," “the Life force that illuminates the universe," and importantly, "all-encompassing Buddha". Therefore, Vairocana is mentioned in different sutras.

Vairocana Buddha is often depicted as seated in the lotus pedal which is supported by a pair of two great lions. Symbolically, it is represented that when the lions roar, all other remains silent and listens to him. Likewise, when one is spreading Buddha's teachings almost all others remains silent and listens to the Buddha's valuable teachings. When Vairocana Buddha is depicted as meditating, it is believed that the image of Vairocana helps to transform the delusion of ignorance into the wisdom preached by the Dharma. Similarly, when Gautama Buddha turned the wheel of Dharma, it illuminated the hearts of people which was darkened by ignorance.

When Vairocana Buddha is depicted in Buddha statues, he is also shown in Dharma chakra mudra. This mudra is formed when the thumb and index finger of both hands touch at their tips to form a circle. The left hand faces inward which covers the right hand which is facing outward and the hands are held against the chest. The remaining fingers of both hands remain extended.

Since Vairocana is believed to be the aggregate of all the Dhyani Buddhas. Therefore, He has the complexion of pure white since white produced when all the colors merge together. His symbol is the dharma wheel. When all Five Dhyani Buddhas are depicted together in a mandala, Vairocana is placed in the center. He is often shown larger than other Buddhas around him. He is Lord of Akanistha Ghanavyuha Pure land which existed in the center. His consort is White Tara and his Bija starts with Om. In Vajrayana Buddhism, it is believed that Vairocana Buddha helps to overcome ignorance and delusion when a person chants his mantra.
