Miyamoto Musashi - A Book of Five Rings

The Book of Five Rings (Go Rin No Sho?) is a text on kenjutsu and the martial arts in general, written by the samurai warrior Miyamoto Musashi circa 1645. It is considered a classic treatise on military strategy, much like Sun Tzu's The Art of War. There have been various translations made over the years, and it enjoys an audience considerably broader than only that of martial artists: for instance, some business leaders find its discussion of conflict and taking the advantage to be relevant to their work. The modern-day Hy?h? Niten Ichi-ry? employs it as a manual of technique and philosophy.
