This is the most helpful, complete, and well-written book on Zen I have ever read. I first read it a couple of months ago, and I continually return to it to re-read chapters, gaining deeper levels of understanding.
Living Zen lives up to its title- a book 'alive' with 'presence and soul'. I would highly recommend this book to anyone curious to go beyond any particular religion or system. Linssen's ideas are not a nebulous form of zen 'instruction' but rather a concrete expression of the connection between physics, science, psychology, biology. This book is the most 'complete' book I have ever read.
