Vairocana

Giant Buddha in Central Plains, Henan, oṃ vairocana hūṃ

Vairocana (also Mahāvairocana) is a cosmic buddha from Mahayana and Vajrayana Buddhism. Vairocana is often interpreted, in texts like the Avatamsaka Sutra, as the dharmakāya of the historical Gautama Buddha. In East Asian Buddhism, Vairocana is also seen as the embodiment of the Buddhist concept of śūnyatā. In Buddhist philosophy, the voidness that constitutes ultimate reality; sunyata is seen not as a negation of existence but rather as the undifferentiation out of which all apparent entities, distinctions, and dualities arise. In the conception of the 5 Jinas of Mahayana and Vajrayana Buddhism, Vairocana is at the centre and is considered a Primordial Buddha.

Vairocana Buddha is first introduced in the Brahmajala Sutra:

Now, I, Vairocana Buddha am sitting atop a lotus pedestal; On a thousand flowers surrounding me are a thousand Sakyamuni Buddhas. Each flower supports a hundred million worlds; in each world a Sakyamuni Buddha appears. All are seated beneath a Bodhi-tree, all simultaneously attain Buddhahood. All these innumerable Buddhas have Vairocana as their original body.

Vairocana is also mentioned in the Avatamsaka Sutra; however, the doctrine of Vairocana is based largely on the teachings of the Mahavairocana Tantra (also known as the Mahāvairocana-abhisaṃbodhi-tantra) and to a lesser degree the Vajrasekhara Sutra (also known as the Sarvatathāgatatattvasaṃgraha Tantra).

In the Avatamsaka Sutra, Vairocana is described as having attained enlightenment immeasurable ages ago and residing in a world purified by him while he was a bodhisattva. He also presides over an assembly of countless other bodhisattvas. He may be considered the celestial existence (saṃbhogakāya) of Gautama Buddha, who came to be as Vairochana's earthly rebirth from his previous existence in Tushita heaven. Similarly, the Brahmajala Sutra also states that Shakyamuni was originally named Vairochana, regarding the former as a physical incarnation (nirmāṇakāya) of the latter.

Vairocana is also mentioned as an epithet of Gautama Buddha in the Samantabhadra Meditation Sutra, who dwells in a place called "Always Tranquil Light". In the Śūraṅgama mantra (Chinese: 楞嚴咒; pinyin: Léngyán Zhòu) taught in the Śūraṅgama sutra (Chinese: 楞嚴經; pinyin: Léngyán Jīng), an especially influential dharani in the Chinese Chan tradition, Vairocana is mentioned to be the host of the Buddha Division in the centre, one of the five major divisions which dispels the vast demon armies of the five directions.

Vairocana is the Primordial Buddha in the Chinese schools of Tiantai, Huayan and Tangmi, also appearing in later schools including the Japanese Kegon, Shingon and esoteric lineages of Tendai. In the case of Huayan and Shingon, Vairocana is the central figure.

Helen Hardacre, writing on the Mahavairocana Tantra, comments that Mahavairocana's virtues are deemed to be immanently universal within all beings: "The principle doctrine of the Dainichikyo is that all the virtues of Dainichi (Mahāvairocana) are inherent in us and in all sentient beings.

Statues

With regard to śūnyatā, the massive size and brilliance of Vairocana statues serve as a reminder that all conditioned existence is empty and without a permanent identity, whereas the Dharmakāya is beyond concepts.

The Spring Temple Buddha of Lushan County, Henan, China, with a height of 126 meters, is the second tallest statue in the world (see list of tallest statues).

The Daibutsu in the Tōdai-ji in Nara, Japan, is the largest bronze image of Vairocana in the world.

The larger of the Buddhas of Bamiyan in Afghanistan that were destroyed was also a depiction of Vairocana.
