Acala

Acala or Achala (Sanskrit: अचल "Immovable") is a dharmapala (protector of the Dharma), prominent in Vajrayana Buddhism and East Asian Buddhism. He is classed among the Wisdom Kings and is preeminent among the Five Wisdom Kings of the Womb Realm. Accordingly, his figure occupies an important hierarchical position in the Mandala of the Two Realms. In China, he is known through esoteric Tangmi traditions as Budong Mingwang ("The Immovable Wisdom King"). In Japan, he is known as Fudō Myōō, which is the on'yomi reading of his Chinese name. Acala is especially important in Japanese Buddhism, where he is venerated in the Shingon, Tendai, Zen, and Nichiren sects, as well as in Shugendō. He is also highly revered among some Yakuza members, who often draw on his intense facial expression and demeanor.In later Tantric scriptures, the epithet Caṇḍaroṣaṇa and Caṇḍamahāroṣaṇa became more common, and he is known as such in countries like Nepal and Tibet.
