To my knowledge this is the only modern book written by an actual Zen Master about the martial arts. Most books are by martial artists writing about Zen, a subject in which they are often lacking in actual practice. Taisen Deshimaru was one of the great Zen masters to teach in the west and the teacher of several great marital arts masters. This book is essential for any serious student of either discapline.
I really got a lot from this book. My Comprehension of karate and the depth in it grew MUCH stronger. I learned the philosophy from the old masters making my karate stronger as well as my confidence. This makes martial arts 10 times more interesting - this'll make you wonder & learn. This is not! a fighting book - this'll give much stronger values.
It gives the person in general and the martial artist in specific a firm ground to understand the Zen foundations of japanese martial arts and way of life. It also creates an alternative view of life that is very useful for the person that studies or works in the fields of psychotherapy & hypnosis.
This book serves as great reminder to those of us in the martial arts who sometimes allow our ego to interfere with our life's mission. Thoughtfully written and communicated. Even those not in the arts would benefit from this book.
