John Daido Loori (1931-2009) was one of the West's leading Zen masters. He was the founder and spiritual leader of the Mountains and Rivers Order and abbot of Zen Mountain Monastery. His work has been most noted for its unique adaptation of traditional Asian Buddhism into an American context, particularly with regard to the arts, the environment, social action, and the use of modern media as a vehicle of spiritual training and social change. Loori was an award-winning photographer and videographer. His art and wildlife photography formed the core of a unique teaching program that integrated art and wilderness training by cultivating a deep appreciation of the relationship of Zen to our natural environment. He was a dharma heir of the influential Japanese Zen master Taizan Maezumi Roshi and he authored many books.
