Tokitsu emphasizes the mental aspects of martial arts practice including:
- The importance of ki development
- Seme, or capturing your opponent's mind
- Understanding ma, the spatial relationship in combat
Studying these concepts, he explains, gives martial artists the tools to train for a lifetime and at the very highest level. Tokitsu also gives a historical and cultural survey of budo, and explains how the Western view of budo training is different than the Japanese--a perspective rarely available to Western martial artists.
