One word sum up this book. Brilliant. An insightful book by a martial artist who is so good a philosopher. This brilliance of this book come from the factthat it is not, like most other books of the martial arts, Aimed at demostrating techniques. It is unique in the sense in fact most of the book is Given to the theory of fighting. What this book teaches is not he particulars of a fight but the way to become a good fighter. The in depth analysis of martial arts in thsi book reveal much more then most other contemporary books on the subject. Most contemporary books has its emphasis on techniques and history of the art but this book places the emphasis on the theory underlying the arts, the simple objective goal of fighting. Hitting and not get hit. I think the main difference between this and other books on the subject is the level of analysis That is Aimed at. It is much more philosophical then other books on the subject. I will demonstrate what I mean by the analogy. If we comapre the subject of "fighting" and That of "time". Then, most books on martial arts are indeed of "how to make the most accurate measurement of time" and this one is on "the nature of time". Overall, a much more philosophical apporach to martail arts then ever thought possible. Written by a person with true knowledge of the art.
