The roots of Zen are clouded with legend; its origins in Chan (Chinese Buddhism), its transmission to Japan, and its transition to a uniquely Japanese tradition are gradual and not identifiable until the 12th century C.E. and later.
Zen includes the wide diversity of the Buddhist pantheon, but also teaches that the divine nature is in all things and that the Buddha-nature is shared by everyone. There is no concept of omnipotent, eternal deities.
