"Endless Vow " is the first English-language collection of the literary works of Soen Nakagawa Roshi. An intimate, in-depth portrait of the master of Eido Tai Shimano, his Dharma heir, introduces the poems, letters, journal entries, and other writings of Soen Roshi, which are illustrated with his calligraphies. In a postscript, some of his best-known American students--including Peter Matthiessen and Ruth McCandless--reminisce about this legendary figure of American Buddhist history.
