Masters in the Japanese arts of Ninjitsu are legendary for their ability to access seemingly endless amounts of pure strength and mental endurance. The Ninja Mind documents Ninjutsu black belt Kevin Casey's journey toward mastery under the tutelage of Stephen K. Hayes, the Black Belt Hall of Fame member and the "Father of American Ninjutsu." Casey vividly describes his successes and setbacks studying with his famous teacher—as well as his growing interest in the Ninja art of Kuji-no-Ho, the most esoteric of traditional Ninja practices. Combined with determination and discipline, Casey's techniques and exercises will guide you to cultivate and acquire a true ninja's power.
