Vairocana Buddha is a central figure in Mahayana Buddhism, particularly in the traditions of Esoteric Buddhism, such as Tibetan and Shingon Buddhism. He is considered to be the embodiment of the Dharmakaya, which is the ultimate reality of all things, and the primordial Buddha from whom all other Buddhas emanate. Vairocana is often depicted in mandalas and other ritual objects as the central figure, surrounded by the other buddhas and bodhisattvas. He is usually shown holding a dharmachakra, which symbolizes the turning of the wheel of the Dharma, and is sometimes depicted with a solar halo to represent his universal nature.In Esoteric Buddhism, the practice of visualizing Vairocana is considered to be an essential aspect of the path to enlightenment. Through visualization practices, practitioners are said to be able to purify their minds, overcome suffering, and attain enlightenment. It is believed that by visualizing Vairocana, one can gain access to the ultimate reality and achieve the state of Buddhahood.In addition to visualization practices, Vairocana is also associated with various tantra practices, such as the mandala ritual and the maṇḍala of the two realms. These practices are used to cultivate compassion, wisdom, and the ability to help others.
