Miyamoto Musashi, was the greatest warrior in Japan and perhaps the world. This amazing 16th century martial artist, philosopher, artist, and teacher. Devised his own style of welding both swords at the same time. He killed 60 men in fights, battles, and duels. Some of his wisdom is captured in his "The book of five rings" and to truly understand its essence, will open your eyes as to how advanced he was and the insight he has passed on to us. As a student of kendo, I had the opportunity of training in Japan. The lesson's learned from the hard life Miyamoto Musashi will greatly benefit any martial artist no matter what style you adhere to.
