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.
