Fudō Myōō and the Wisdom Kings of Japanese Esoteric Buddhism

Fudō Myōō (不動明王), the "Immovable Wisdom King", is the Japanese form of the Indian Buddhist deity Acala or Acalanātha, a wrathful protector who serves the cosmic Buddha Mahāvairocana and burns away delusion with a sword and a halo of flames. Brought to Japan with esoteric Buddhism in the ninth century, he became the most widely worshipped of the myōō or wisdom kings, the central deity of the goma fire ritual and a patron of mountain ascetics, warriors and ordinary believers alike.

From Acala to Fudō: Origins of the Wisdom Kings§

The wisdom kings arose in the Indian tantric Buddhism of the seventh and eighth centuries, in which spells (vidyā, mantra, dhāraṇī) were believed to hold the power of enlightened beings. Their personifications took the terrifying forms of protective deities so that they could subdue demons, obstacles and human passions that peaceful buddhas would not confront directly. Acala, "the Immovable", appears in the Mahāvairocana Sūtra (in Japanese, Dainichikyō), a central scripture of esoteric Buddhism compiled in India in the seventh century and translated into Chinese in 724–725, as a servant and messenger of the Buddha who removes hindrances from practitioners.

In India and Tibet Acala remained a relatively minor figure. In Tang China, and above all in Japan, he grew in importance. When Kūkai returned from China in 806 and founded the Shingon school (see Shingon and Tendai esoteric Buddhism), he brought ritual texts and images of the wisdom kings, and Japanese commentators came to interpret Fudō as the "wheel-turning body of command" (kyōryōrinjin) of Dainichi himself: the Buddha's compassion taking a fearsome form to discipline those who cannot be reached by gentleness.

Iconography of Fudō Myōō§

Japanese images of Fudō follow a set of conventions codified in the ninth century, notably in a list of nineteen visualised features attributed to the Tendai scholar Annen. Fudō is a stout, youthful figure with a dark blue or black body, the colour of a storm cloud. He sits or stands on a rough rock base, a sign of his immovability, before a mandorla of flames often shaped like the wings of the mythical bird karura (the garuda).

• In his right hand he holds a sword, which cuts through ignorance; on some images it is the Kurikara sword, around which a dragon coils.
• In his left hand he holds a lasso (kensaku), with which he binds the passions and draws beings toward salvation.
• His hair is gathered in a braid over his left shoulder, and in many images one eye stares upward and the other down, while one fang points up and the other down, signs of his power over heaven and earth.
• He is often accompanied by two youthful attendants, the gentle Kongara and the scowling Seitaka, and sometimes by a larger group of eight.

Some images became famous in their own right. The "Yellow Fudō" of the Onjōji (Miidera) is said to record a vision of the deity by the Tendai monk Enchin in the ninth century, while the "Red Fudō" of Mount Kōya and the "Blue Fudō" of the Shōren'in in Kyoto are celebrated masterpieces of Buddhist painting. Cynthea Bogel has shown how such images were understood not merely as pictures but as vehicles through which the deity became present to the practitioner.

The Five Great Wisdom Kings and Other Myōō§

Fudō is usually grouped with four other wisdom kings as the Godai Myōō, who protect the centre and the four directions:

• Fudō (Acala) at the centre;
• Gōzanze (Trailokyavijaya, "Conqueror of the Three Worlds") in the east, shown trampling the Hindu god Maheśvara and his consort, an image of Buddhism subduing rival powers;
• Gundari (Kuṇḍalī) in the south, entwined with serpents;
• Daiitoku (Yamāntaka, "Destroyer of Death") in the west, with six faces, six arms and six legs, riding a water buffalo;
• Kongōyasha (Vajrayakṣa) in the north, replaced in the Tendai school by Ususama (Ucchuṣma), the deity of purification who is enshrined in temple toilets.

The finest early group survives in the lecture hall of Tōji in Kyoto, where Kūkai planned a sculptural mandala completed in 839. Outside the group, Aizen Myōō (Rāgarāja), red-bodied and bearing a bow and arrow, embodies the transformation of desire into enlightenment and was popular among those praying for love, while Kujaku Myōō (Mahāmayūrī), a peaceful bodhisattva-like figure riding a peacock, was invoked against poison, disease and drought; the legendary founder of Shugendō, En no Gyōja, was said to have mastered the Peacock King's spell.

The Goma Fire Ritual§

Fudō's cult is inseparable from the goma (from the Sanskrit homa), the fire offering adapted from the Vedic sacrifice by Indian tantric Buddhists. In a Shingon or Tendai temple the priest sits before a square or round hearth set in front of an image of Fudō, with ritual implements arranged on the altar. Through mudrās, mantras and visualisations he invites the deity into the fire, offers grains, oil, incense and wooden sticks, and then sends the deity away. Richard Payne's study of the Shingon fire ritual describes how the rite is structured as a sequence of offerings to several deities in turn, and how the fire is understood both outwardly, as a meal for the gods, and inwardly, as the fire of wisdom consuming the practitioner's defilements.

Lay believers take part by writing prayers on thin wooden sticks (gomagi), which are burned during the rite. Large public goma are held at major Fudō temples, and the mountain ascetics of Shugendō perform an outdoor version, the saitō goma, on a great pyre of cedar branches, sometimes followed by fire-walking over the embers. In the Heian period the court commissioned elaborate goma and other esoteric rites, including the Rite of the Five Altars (godanhō), in which all five wisdom kings were invoked at once for the health of the emperor, for safe childbirth or for the defeat of rebels.

Fudō in Japanese Religion and Society§

Fudō became a protector for many kinds of people. Shugendō practitioners regard him as their principal deity, and images of Fudō stand beside the waterfalls where ascetics perform takigyō, standing under falling water while reciting his mantra. Warriors honoured him as an unshakeable guardian. The temple of Narita-san Shinshōji east of Tokyo traces its origin to 940, when, according to temple tradition, a Fudō image was brought from Kyoto to pray for the suppression of the rebel Taira no Masakado; in the Edo period its image was exhibited in the capital to great crowds, and the kabuki actors of the Ichikawa Danjūrō line adopted it as their patron.

Stories of Fudō's compassion circulated widely. A famous tale, illustrated in a fourteenth-century scroll, tells of a painted image that wept when a young monk offered to take on his master's fatal illness; Fudō took the disciple's place himself. The yin-yang master Abe no Seimei appears in that story as the ritualist who transfers the illness, a reminder of how closely esoteric Buddhism and onmyōdō were entwined at court. Urban temples such as Meguro Fudō in Tokyo drew crowds on the deity's monthly fair day, the twenty-eighth, and Fudō halls and images are found at many stations of the Shikoku pilgrimage on Kūkai's home island.

Wrath as Compassion: Interpreting the Wisdom Kings§

To visitors unfamiliar with Vajrayāna Buddhism, the furious faces of the wisdom kings can seem at odds with Buddhist ideals of peace. Esoteric teachers explain their anger as compassionate: just as a parent may scold a child to save it from danger, the wisdom kings frighten and bind the forces that keep beings from awakening. The doctrine of the "three wheel-bodies" in Shingon distinguishes the Buddha's own body, the gentle body of the bodhisattva and the stern body of command embodied in the myōō.

Historians such as Bernard Faure have emphasised a further dimension: the wisdom kings show how medieval Japanese religion absorbed and subordinated other gods. Gōzanze's trampling of Maheśvara and Fudō's binding of demons expressed the triumph of Buddhist ritual over unruly powers, and in combination with Shinto and Buddhist fusion such deities were enshrined beside kami and invoked in local rites of healing and protection. Today Fudō remains one of the most familiar figures in Japanese religious art, and his fire ritual is among the most frequently performed esoteric ceremonies in Japan.

Frequently asked questions§

Who is Fudō Myōō?§

Fudō Myōō is the Japanese name of Acala, the "Immovable" wisdom king of esoteric Buddhism. He is regarded as a wrathful manifestation of the Buddha Dainichi who protects practitioners and destroys delusion, and he is the main deity of the goma fire ritual.

Why does Fudō Myōō look so angry?§

His fierce expression represents compassion in a stern form. In esoteric Buddhist teaching, the wrath of the wisdom kings is directed against ignorance, passions and obstacles, and is meant to frighten beings out of harmful ways rather than to harm them.

What are the Five Great Wisdom Kings?§

They are Fudō at the centre, Gōzanze in the east, Gundari in the south, Daiitoku in the west and Kongōyasha in the north (Ususama in Tendai). They were often invoked together in court rituals for protection and healing.

What is a goma ritual?§

Goma is the esoteric Buddhist fire offering, derived from the Indian homa, in which a priest makes offerings into a sacred fire before an image of Fudō. Wooden sticks inscribed with believers' prayers are burned, symbolising the burning away of defilements.
