Shugendo: Pilgrimage and Ritual in a Japanese Folk Religion, Paperback/Andrea Gill

The religion of Shugend has no shrines, and it has no temples. It only has the liminality of the mountains, a space that is viewed in Japan as being ground that only gods, demons, and ghosts may set foot on. But the Yamabushi are not human, gods, or even demons. Instead, they are believed to be living Buddhas, rare people that, through practice in the secluded mountains, have become privy to sacred knowledge that has awakened them to their intrinsic Buddha-nature, to borrow the words of Kukai, "in this very lifetime." One of the defining features of Shugend is the relationship that is formed between man, gods, and nature in the context of the sacred mountain (Grapard, 1994). Another feature found strongly in Shugend is the role that the Yamabushi plays in the communities surrounding their holy mountains.
