The lovely Otsu, seeing in Musashi her ideal of manliness, frees him from his tortuous punishment, but he is recaptured and imprisoned. During three years of solitary confinement, he delves into the classics of Japan and China. When he is set free again, he rejects the position of samurai and for the next several years pursues his goal relentlessly, looking neither to left nor to right.

Ever so slowly it dawns on him that following the Way of the Sword is not simply a matter of finding a target for his brute strength. Continually striving to perfect his technique, which leads him to a unique style of fighting with two swords simultaneously, he travels far and wide, challenging fighters of many disciplines, taking nature to be his ultimate and severest teacher and undergoing the rigorous training of those who follow the Way. He is supremely successful in his encounters, but in the Art of War he perceives the way of peaceful and prosperous governance and disciplines himself to be a real human being.

He becomes a reluctant hero to a host of people whose lives he has touched and been touched by. And, inevitably, he has to pit his skill against the naked blade of his greatest rival.

Musashi is a novel in the best tradition of Japanese story telling. It is a living story, subtle and imaginative, teeming with memorable characters, many of them historical. Interweaving themes of unrequited love, misguided revenge, filial piety and absolute dedication to the Way of the Samurai, it depicts vividly a world Westerners know only vaguely. Full of gusto and humor, it has an epic quality and universal appeal.
