Written around 1645, Miyamoto Musashis Five Rings is a classic Japanese work on mastery in swordsmanship, leadership and conflict. Musashi was a swordsman, philosopher and strategist, and today his work remains of influence not only in the realm of martial arts but in the business world, too. Musashis no-nonsense approach to the martial arts and combat includes eliminating technical flourishes, understanding that technique should simply be understood as defeating your opponent, and appreciating that the same qualities apply in both small- scale and large-scale conflicts. Repeatedly, he stresses the importance of learning through practice, rather than merely reading about them.
