Yugen-Do is the elegant path, a Zen understanding of time (U-JI) and the sacred. An original SUTRA or work that is teaching, and not an academic text, this book explores several ZEN traditions which are at a deeper level than the first ZEN teaching and is a follow on work to "Descending the Mountain" which is a first introduction to Zen Buddhism. Yugen-Do is a discourse on Dogen's "Walking Mountains Sutra" and takes you on a journey through many great zen masters and teachers arriving at a final understand of this more esoteric teaching of ZEN.
