Immovable (1) ［不動明王］ ( Achala or Achalanātha; Fudō-myō’ō): The wisdom king Immovable. Immovable is a main deity among the wisdom kings, a group of deities who are said to remove all obstacles and defeat all devils that hinder Buddhist practice. He is regarded as the leader of the five great wisdom kings, the other four being Conqueror of the Threefold World, Kundalī, Great Awesome Virtue, and Diamond Yaksha, as well as of the eight great wisdom kings (the above five deities plus Ucchushma, Unconquerable, and Horse-Headed). It is said that he enters the flame-emitting meditation in which he emits flames that destroy all karmic hindrances. Because he remains unperturbed by obstacles, he is called Immovable. He is popularly depicted as an angry figure surrounded by flames, holding a rope and a sword. The Sanskrit name achala means immovable, and nātha means a lord or a protector. See also flame-emitting meditation.
