(Skt: Ragaraja) A Buddhist deity who is said to purify people's afflictions and free them from illusions and the sufferings accruing from afflictions. In the esoteric teaching his true identity is regarded as Dainichi (Skt: Mahavairochana) Buddha or Kongosatta (Vajrasattva). Aizen is pictured on the Diamond World mandala and is depicted as being red in color with three eyes, six arms and a furious expression. In his hand he has a bow and arrows. His name is inscribed in Siddha, a medieval Sanskrit orthography, on the left-hand side of the Gohonzon as one faces it, signifying the principle that afflictions are enlightenment (Jap: bonno soku bodai).
