Rāgarāja is considered a Vidyaraja or "Great Wisdom King", in keeping with others like Acala and Gozanze. There are four different mandalas associated with Rāgarāja. The first posits him with thirty-seven assistant devas, the second with seventeen. The other two are special arrangements, one made by Chisho Daishi, fourth patriarch of the Tendai sect, the other a Shiki mandala which represents deities using their mantra seed syllables drawn in bonji.
