"Shortly before his death in 1645, undefeated swordsman and wandering samurai Miyamoto Musashi retreated to a cave to live as a hermit. There he wrote five scrolls describing the 'true principles' required for victory in the martial arts and on the battlefield. Instead of relying on religion or any theoretical approach, Musashi based his writings on his own experience, observation, and reason. The Book of Five Rings explores the psychological strength, rigorous self-control, and practical application necessary for dealing with physical and mental conflict. Since it first appeared, this delineation of samurai technique and philosophy has been celebrated internationally as a tool for shaping business strategy, resolving conflict and achieving success."
