Miyamoto Musashi was the greatest swordsman to ever come out a nation of great swordsmen - Japan. His story, which has become the basis for countless flying swordsman Oriental movies, is one of raw courage, unbridled ambition and unparalleled mindfulness. In one on one combat he defeated 60 opponents, yet his greatest legacy is his seminal work, the Book of Five Rings, which is still pored over my military tacticians and mindfulness enthusiasts 450 years after it was written.
