In this clarifying new commentary, esteemed Zen teacher Shinshu Roberts takes readers on a journey to understand Japan's great Buddhist philosopher. In addition to a full translation of Dōgen's "Genjōkōan", this book includes the commentary Okikigakishō ("Notes of What Was Heard and Extracted"), written by two of Dōgen's direct students - the first time an English translation of this highly influential work has appeared in print.
