More importantly, by understanding motion, and dealing with live, moving opponents in Kosho training, students also study when the target is exposed and in the ideal yin state to accept the blow we choose with maximum effect. The study of the combination of tsubo-targets, natural movement and rotation, angle of rotation, breathing, and posturing in relationship to the strike and striking angle determine the type of blow used, and its effect. In addition to striking arts, grappling arts and throwing arts are covered at length in Kosho Ryu schools. The same laws and principles apply to both. Furthermore, Kosho Ryu sees no difference between striking arts and throwing arts other than intent.
Rotation takes place in all motion.
By studying natural laws of motion and balance, we can understand kuzushi, imbalance. All movement requires a temporary state of imbalance to regain the next balance point. Without imbalance, movement is impossible. Movement is a falling process . Therefore, when we continue the imbalanced movement of an attacker, we make it impossible for him to regain balance.
