abstract:In Vajrayana Buddhism, a Wisdom King (Sanskrit विद्याराज vidyārāja, Chinese Míngwáng 明王, Japanese 明王 myō-ō) is the third type of deity after Buddhas and bodhisattvas. The Sanskrit name literally "king of knowledge", thus the Chinese character "明", meaning knowledgeable (and/or bright) is used, leading to wide array of alternative English names including Radiant King, among others like Guardian King, etc.
