The mastery of a martial art comes by cultivating one1s inner mastery. Kenji Tokitsu shows how cultivating ki and understanding the principles of budo can make training in martial arts more meaningful, effective, and rewarding. In addition to cultivating ki, his approach to training emphasizes mental aspects including seme, capturing your opponents mind, and ma, the spatial relationship in combat. Although Tokitsu is best known as a karate master, the book is written for all practitioners of Japanese martial arts, including kendo, judo, and aikido.
