Vairocana is the cosmic buddha of the Avataṃsaka Sūtra and of esoteric Buddhism, and his Sanskrit name means “belonging to the sun”. In the Avataṃsaka and in Huayan (Japanese Kegon), the Mahāyāna school built on it, Śākyamuni and countless other buddhas are his manifestations, and Nara’s Great Buddha is his image. As Mahāvairocana, in Japanese Dainichi (“Great Sun”), he sits at the centre of Shingon’s two great maṇḍalas, and in Tibetan, Nepali and Javanese art he takes the chief place among the five buddhas.

What does Vairocana mean?

The name is formed from virocana, “shining upon, brightening, illuminating”, a word that as a noun means the sun; Monier-Williams’s Sanskrit dictionary glosses vairocana itself as “coming from or belonging to the sun, solar”. Franklin Edgerton’s dictionary of Buddhist Hybrid Sanskrit gives “the sun” as its first sense and, as a proper name, lists Vairocana first of the five “transcendent” buddhas, Tibetan rnam par snang mdzad, which Britannica renders “Maker of Brilliant Light”. Both dictionaries also record Vairocana as the name of a meditative absorption (samādhi).

In Pāli the word is verocana, “the sun” in the Pali Text Society’s dictionary. When Rāhu, lord of the titans, seized the Sun God, the Buddha told him to let go:

The Pāli behind “the dazzling sun” is verocano. East Asia transliterated the name and translated it. Chinese wrote Piluzhena (毘盧遮那), shortened to Lushena (盧舍那); Japanese reads these Birushana and Rushana, also Roshana, and Korean Birojana and Nosana. Mahāvairocana was translated as “Great Sun”, 大日, Japanese Dainichi, or as (Dai)henjō, “(Great) Universally Illuminating One”. Tōdai-ji explains its Great Buddha as the buddha “the light of whose knowledge and compassion illumines widely”.

Vairocana in the Avataṃsaka Sūtra and Huayan

Vairocana first takes a central role in the Avataṃsaka Sūtra, the “Flower Garland”. In the sutra Śākyamuni is only one of countless manifestations of Vairocana, and is even called by his name. Vairocana prayed to appear in this way, in countless worlds at once, and the bodhisattvas those buddhas teach were once his own pupils. The sutra’s last chapter, The Stem Array (Gaṇḍavyūha), tells the story of the birth in the Lumbinī grove as Vairocana’s, and Queen Māyā says to the pilgrim Sudhana:

The Brahma Net Sutra (Fanwang jing), a text composed in China that drew on Avataṃsaka teachings, supplied the image that the colossi of Longmen and Nara follow (see below). It seats Vairocana on a lion throne in the Lotus Treasury World, and a verse describes the scene in his voice:

The sutra also sets rules for monastics and lay people, rulers included (see bodhisattva vows).

In China the Huayan school, based on the Avataṃsaka, enjoyed the patronage of Empress Wu Zetian in particular (see Buddhism in China). Its picture of one omniscient buddha presiding over innumerable worlds, each with a buddha of its own, was likened to a ruler over a centralised state, and it helped Wu, who saw herself as a universal monarch, to present herself as an absolute sovereign. Vairocana’s typical attendants are the bodhisattvas Mañjuśrī, on a lion, and Samantabhadra, on a six-tusked elephant; in China the three are known as the Three Saints of Huayan.

In Japan the school is Kegon, and its head temple is Tōdai-ji in Nara. As expositor of the Kegon scriptures, in which he pervades the entire universe, Vairocana is normally called Rushana. In 749, the temple records, Emperor Shōmu made it clear that he held the Avataṃsaka to be the most fundamental of all Buddhist texts.

Mahāvairocana, the Great Sun of Shingon

In esoteric Buddhism (Japanese mikkyō) Vairocana eventually took the place of Śākyamuni as expositor of the teaching and became the centre of the pantheon. Two scriptures that reached China from India give him that place, and East Asian esoteric Buddhism still treats them as its two basic texts.

The Vairocanābhisaṃbodhi, better known as the Mahāvairocana Sūtra (Japanese Dainichikyō), is known in no Sanskrit manuscript, though other Sanskrit works quote passages from it. Śubhākarasiṃha (637–735) and his disciple Yixing (683–727) translated it into Chinese in 724–5, and a Tibetan translation followed early in the ninth century. Most of it is a dialogue between the Buddha Vairocana and Vajrapāṇi, “Lord of Mysteries”. Asked the cause, root and culmination of the knowledge of an omniscient one, Vairocana answers:

Those three propositions — bodhicitta, compassion and skilful means — are considered to sum up the whole sūtra. The second text, the Sarvatathāgatatattvasaṃgraha (Japanese Kongōchōkyō, “Diamond Peak Sutra”), describes the Diamond Realm maṇḍala.

Kūkai (774–835), the founder of Shingon, came upon the Dainichikyō in Japan and travelled to China in 804 to study it. In Chang’an the master Huiguo (746–805) initiated him into both lineages, one centred on the Diamond (Vajradhātu) maṇḍala, the other on the Womb (Garbha) maṇḍala of the Mahāvairocana Sūtra; he returned in 806. The two maṇḍalas had evolved separately in India; Huiguo is thought to have paired them as paintings, and Kūkai taught that the two are not two. Dainichi is at the centre of both, with partly different buddhas around him. The Womb maṇḍala, the “mandala of principle”, and the Diamond, the “mandala of wisdom”, customarily hang facing each other on the eastern and western walls of a hall, in Tendai as in Shingon (see Buddhist mandala and Buddhism in Japan).

Unlike other buddhas, Dainichi is shown as a bodhisattva, in silk robes, armlets and bracelets, wearing a five-wisdom crown that marks his identity with the five buddhas. He is generally white, and his mount is the lion. In Shingon he is the chief object of reverence and is regarded as the source of the entire universe. On Mount Kōya, where Kūkai founded his monastery, the Konpon Daitō pagoda, which Kūkai called a representation of the universe, enshrines a Womb Realm Vairocana surrounded by four figures of the Diamond Realm. The fierce wisdom king Fudō Myōō is Dainichi’s representative, a transformation of him in fierce form (see wisdom kings).

Is Vairocana the dharmakāya?

It depends on the text. Mahāyāna speaks of three bodies of a buddha: the dharmakāya, the embodiment of the Dharma; the saṃbhogakāya, the “embodiment of bliss”; and the nirmāṇakāya, the earthly “embodiment of transformation” (see one buddha, three bodies).

Shingon answers yes. In the summary of the Stanford Encyclopedia of Philosophy, traditional Mahāyāna treats the dharmakāya (Japanese hosshin) as an abstract principle, impersonal and non-preaching. For Kūkai it is the Buddha Dainichi, who preaches the Dharma by concretising it in the cosmos as his own body. The Dainichikyō had named its central buddha with a sun metaphor but left his identity with the dharmakāya ambiguous; Kūkai is regarded as the first to set it out systematically. On this view exoteric teachings go back to Śākyamuni, esoteric ones directly to Dainichi.

Other sources draw a finer line. Rolf Giebel’s glossary to the Vairocanābhisaṃbodhi assigns Mahāvairocana to the Dharma body and Vairocana to the enjoyment body, “although the two are sometimes used interchangeably”, and some Buddhists regard Mahāvairocana as a being separate from the Vairocana who is one of the five buddhas. Himalayan art shows two main types of Vairocana: buddha (nirmāṇakāya) appearance and ornamented, peaceful (saṃbhogakāya) appearance.

Vairocana among the five buddhas and in Tibet

In the Vajrayāna set of the five wisdom buddhas, Vairocana heads the Buddha family, is coloured white and usually sits at the centre; in Japan’s Diamond Realm his is the wisdom of the essence of the Dharma-realm, which embraces the other four wisdoms. In Nepali, Tibetan and Javanese art he is often considered the progenitor of the other four, or even the primordial buddha himself. The centre is not fixed. 84000’s introduction to The Stem Array holds that even in the higher tantras Vairocana keeps his place as the central buddha of the five families, yet in the Guhyasamāja maṇḍala Akṣobhya takes the centre and Vairocana the east. At the Svayambhu stupa in Kathmandu the four buddhas of the directions sit in niches in the dome; Vairocana, whose place is the centre, was eventually given a niche of his own just south of Akṣobhya, which, in Alexander von Rospatt’s words, “defies the logic of the mandala” (see Buddhism in Nepal).

His cult was prominent in Tibet’s imperial period. In 804 and 806 a meditation master from a monastery near Lake Kokonor commissioned stone carvings of a crowned buddha on a lion throne among eight bodhisattvas, at Denma Drak in Kham and at Bimda Temple near Jyekundo. Inscriptions beside them record the circumstances, the artists’ names and prayers concerning Vairocana in the closing section of the Gaṇḍavyūha. They are the earliest dated Tibetan art yet known, and the art historian Amy Heller reads their Vairocana as standing for the Tibetan emperor.

As the central figure of a Himalayan painting he belongs mainly to the Caryā and Yoga tantras: the Vairocanābhisaṃbodhi, the Tattvasaṃgraha and the Sarvadurgatipariśodhana. In one of the Tattvasaṃgraha’s two forms he is white and four-faced, holding a five-pointed vajra with both hands in the gesture of supreme enlightenment. In the Anuttarayoga tantras he is one of the five, white and peaceful, his hands in the teaching gesture (see Tibetan Buddhism). A seated meditation posture also bears his name: Tibetan writers most often expound the seven-point posture of Vairocana from Kamalaśīla’s Bhāvanākrama, though other buddhas such as Amitābha share it (see meditation posture).

Great images of Vairocana

Colossal size, the art historian Dorothy Wong argues, became a metaphor for the cosmic dimension of buddhahood, and came to symbolise the authority of rulers too. For fuller histories, see giant Buddha statues and the greatest Buddhist monuments.

The Longmen Vairocana’s cosmology is the Avataṃsaka’s, but its iconography, a buddha atop a lotus whose every petal holds a world, comes from the Brahma Net Sutra. The Tōdai-ji image follows the same pattern and stood about 16 metres tall when completed in 752, larger than the restored statue of today. An ink inscription inside the pedestal of the Enjō-ji Dainichi records that Unkei began it in the first year of the Angen era (1175) and delivered it in the second (1176), after about eleven months’ work under the direction of his father, Kōkei.

Mudrās and the Mantra of Light

Dainichi’s two Japanese mudrās match the two maṇḍalas. In the Diamond Realm he forms the knowledge fist (chiken-in): the clenched right hand grasps the raised forefinger of the otherwise clenched left. In India it was called jñānamuṣṭi or bodhyagrī, and Indo-Tibetan iconography generally used the second name, the “mudra of supreme enlightenment”, the name also given to the gesture of the Tattvasaṃgraha’s Vairocana in Tibetan art. Japanese esoteric tradition reads the left hand as sentient beings and the right as the buddhas, so the gesture stands for their mutual response; Britannica calls it the “mudra of the six elements”, uniting matter with consciousness. In the Womb Realm his hands rest in his lap, right over left, palms up and thumbs touching, in the concentration seal of the Dharma-realm (hokkai jōin).

One of the most famous mantras in Japan is the Mantra of Light (kōmyō shingon). Japanese reference works call it the mantra of Dainichi Nyorai and a general spell of all buddhas and bodhisattvas, and read it on abogya beiroshanō makabodara mani handoma jinbara harabaritaya un. It appears in a short text translated by Amoghavajra whose Chinese title names Vairocana (T1002). The text promises that sand empowered 108 times with the mantra and scattered over the dead, or on their graves, frees them from the retribution for their wrongs, even in the hells, and brings rebirth in the western Land of Utmost Bliss. Tendai and Shingon use it in services and in rites such as segaki, the offering to hungry ghosts. In medieval Japan the older schools promoted it as better than the nembutsu; it spread bound up with Pure Land thought and was carved on stone memorial stupas (see Buddhist mantras).

How the traditions differ

Theravāda. The Pāli canon that Theravāda keeps as scripture names no buddha Vairocana. A search of SuttaCentral’s Pāli texts finds verocana only as the sun or as a name, for instance of Verocana, lord of the titans, and never as the name of a buddha. In SN 11.8 Verocana and Sakka, lord of the gods, stand at the Buddha’s door and argue whether effort or patience wins a goal; Bhikkhu Sujato glosses the name “son of Virocana” (Agni or the Sun). Sanskrit literature likewise uses Vairocana as the patronymic of Bali, son of the asura Virocana. The cosmic buddha belongs to the Mahāyāna and its tantric traditions.
