He is considered one of the greatest swordsmen of all time. No other samurai achieved the fame of this one: Miyamoto Musashi. He wrote this book for his adopted son. It is a guide to the Ichi school that Musashi developed over his more than sixty years of life. What sets it apart from other well-known sword fighting techniques is a style that borders on purism, which can be applied not only to martial arts but also to life itself. The five paths or sections of the book are aligned with the five paths of Buddhism, demonstrating that all perfection culminates in emptiness and that a true master makes no distinction in his life between sword fighting and any other art form.
