Yagyu was a renowned swordsman and chief of the Shogun's secret police, while Takuan was the Zen spiritual mentor to the Emperor. This samurai philosophy book contains the first English translations of their seminal writings on Bushido. Cleary not only provides clear and readable translations but comprehensive notes introducing the social, political, and organizational principles that defined samurai culture—their loyalty to family, their sense of service and duty, and their political strategies for dealing with allies and enemies.
