Review: It has been a long while since I read this book. I can tell you this much, I read it about four time consecutively, it was that good and well written. I actually got in contact with the author who had a manuscript, rough, in the works for a follow up book but much to our loss he passed on to the greater dojo above and now practices with others like Shimabuku Tatsuo Sensei.
His philosophical outlook was inspiring and this book is worth not only the money but the frequent readings and references.
