The story is full of the true face of the Soke, which he usually only shows to his students at the dojo! This book is packed with the "teachings" rather than the "techniques" of "martial arts for survival". This book is full of the secrets of "how to live" that are not taught in schools. Regardless of whether you are a martial artist or not, I hope that you will read this book and grasp the "art of survival" if you feel that life is hard or painful.
