John Daido Loori was, until his death in 2009, the spiritual leader and abbot of Zen Mountain Monastery in Mt. Tremper, New York. Trained in koan Zen as well as in the subtle school of Master Dogen's Zen, he was the Dharma heir of Hakuyu Taizan Maezumi Roshi. Devoted to maintaining authentic Zen training, he developed a distinctive style, called the Eight Gates of Zen, based on the noble eightfold path. Drawing on his background as scientist, artist, naturalist, and Zen priest, Abbot Loori was an American master who spoke directly to students from the perspective of a common background. His books include Mountain Record of Zen Talks and The Heart of Being. Thomas Yuho Kirchner was born in Baltimore, Maryland, in 1949.
