The Godai Myō-ō are warlike and wrathful deities who represent the power of Buddhism to overcome the passions.
Five of the Myō-ō are emanations of the Five Buddha of Wisdom, and in this role they guard the four cardinal directions and the center.
The teachings of Esoteric Buddhism are mystical and hard to understand, and require a high level of devotion and austerity to master.
Elaborate and secret ritual practices are used to help partitioners develop and realize the eternal wisdom of the Buddha.
This form of Buddhism is not taught to the general public, but is confined mostly to Buddhist believers, priests and like Ryoshi those far along the path toward enlightenment.
