What Is Acala (Fudō Myōō)

Acala is the most widely revered Wisdom King in Japan and a principal deity for prayers that avert misfortune and calamity. At Byōdōji, the Acala goma is performed on the night of the 28th of every month.

A Wisdom King is a deity who guides in a deliberately severe form when calm instruction alone does not reach a person. Shingon teaching places Acala as a representative executor of Mahāvairocana's command. Acala and Mahāvairocana retain distinct names and forms; their relationship is one of activity and embodiment, not a simple claim that they are the same deity.

Acala abides amid flames. With the sword in his right hand he severs delusion; with the lasso in his left he draws in those who are lost. Seated upon the great rock, he expresses a concentration that no outer event and no inner defilement can shake.

In Sanskrit, Acalanātha. The name means "the Immovable One." He is also called Shō Mudō-son, the Sacred Immovable One.

One text that describes Acala as a manifestation of Vairocana is the Ritual Manual for the Secret Attainment of the Forty-Eight Messengers of the Victorious Acala. The work is transmitted under the attribution "compiled by Amoghavajra and Prajñā"; it promises protection, life after life, to those who form a bond with Acala's mantra.

Fudō's form is described in detail in the ritual manuals. A single braid of hair hangs down on the left, one eye is narrowed, the right hand grasps a sharp sword, the left holds a lasso, he is seated upon a great rock, and his body is dark blue-black in color.

Goma is an esoteric rite in which the sacred fire of wisdom is kindled in the hearth and offerings are made. The Mahāvairocana Sūtra teaches both outer and inner goma. Elsewhere, it compares the Buddha's wisdom, which consumes ignorance, to fire. The verse below is that comparison.

A representative Japanese Shingon arrangement places Acala at the center and four Wisdom Kings around him: Trailokyavijaya, Kuṇḍali, Yamāntaka, and Vajrayakṣa. Their groupings and directional assignments vary among texts and lineages, so this is an important pattern rather than the only possible one.

The Mahāvairocana Sūtra also assigns Acala a place southwest of Mahāvairocana in its instructions for the maṇḍala. As a principal deity of pacifying rites, Acala has long occupied a central place in the practice of esoteric Buddhism.

Fudō is the Wisdom King most beloved in Japan, the principal deity of prayers for worldly benefit.

Byōdōji, the twenty-second station of the Shikoku Eighty-Eight Sacred Sites and a temple of the Kōyasan Shingon school, holds deep devotion to Fudō and performs the Fudō goma on the night of the 28th of every month. The 28th is Fudō's ennichi.

The Acala enshrined at Byōdōji is a seated image in joined-woodblock construction (yosegi-zukuri), held to date from the Edo period. He grasps an upright sword in his right hand and a lasso in his left, with the heaven-and-earth eyes and bared fangs of a wrathful form.

At Byōdōji, the Shōhassenmai-ku (offering of eight thousand burnt sticks) and the Two-Hundred-Twenty-Thousand-Stick goma held each year are also performed as great rites with Fudō as the principal deity. The monthly Fudō goma is the everyday heart of this devotion.

Prayers for warding off misfortune, averting calamity, and preserving life are entrusted to the sacred wisdom-fire of the goma. The fierce face is not there to drive people away. It embodies a compassion willing to cut through delusion in order to save—and that is the vow renewed in Byōdōji's monthly practice.
