About Wisdom King

In Vajrayana Buddhism, a Wisdom King is a type of deity in Buddhism and classed as the third after buddhas and Bodhisattvas in Japanese statuary. The Sanskrit name literally translates to "knowledge king", thus the Chinese character "明", meaning "knowledgeable", or "bright" is used, leading to wide array of alternative English names, including "Radiant King", "Guardian King", etc. In Tibetan Buddhism, they are known as Herukas.
