Dainichi Nyorai is the principal deity of Shingon Esoteric Buddhism and the Buddha, the compassionate mother of all beings.
Although we often see Kannon Bodhisattva on a dragon, this work depicts Dainichi Nyorai on a dragon.
The entire universe is Dainichi Nyorai. It is said that the entire universe is concentrated in Dainichi Nyorai, the A-syllable, and that everything flows out from the A-syllable.
