In the final days of his life, the mythical Japanese samurai Musashi Miyamoto retreated to a cave called the Reigandō. (Spirit Rock Cave) In that cave he spent the final months of his life meditating and writing his views on the world. While secluded in the cave he wrote two works. The Go Rin No Sho (Book of Five Rings) and the Dokkōdō. The Go Rin No Sho he imparted with all of his samurai martial arts. The Dokkōdō contains his very own soul. Each of these books are the result of years of his life spent as a samurai and ronin. While the works themselves speak of Japanese culture and sophistication, especially in the warrior class, he also speaks of strategy, combat, and of the arts.
Both of these works are dedicated to his favorite disciple Terao Magonojo.
