In order to move together with your opponent finding the right way of Taekwondo you should control yourself according to the rhythm of motion and have your will ride the change. The origin that makes everything exist is the driving force that generates all changes of everything, which has been called <Do> on one hand and it has been also called <Yeok>¹⁾ on the other hand. <Do> is the name given from the view of "not-being" to refer to the nondistinctive figure of the absolute²⁾ while <Yeok> is the name given from the view of "being" to refer to it.³⁾

What is or is not? The what is or is not is verily the distinction, and since there is no distinction there can be <Do> that never changes penetrating everything, while since there is distinction each can be different from another, which produces changes with <Yeok> that presents all kinds of changes in the world. With full understanding of it you will come to know that <Do> and <Yeok> are open to each other, not different at all.

The rhythm, which is immanent in change, generates Yin and Yang through <Yeok> while it also produces Kang and Yu through <Do>, so since those four of Yin, Yang, Kang and Yu compose Man(Saram) and the composition proceeds as breath there can be distinctions between Yin and Yang and between Kang and Yu only after Man(Saram). Therefore, the Samjae of Haneul(Heaven), Tang(Earth) and Saram(Man) cannot be its exception, and neither can be everything of Taekwondo.

When you are to find this sort of change in Taekwondo the best example would be that in distance. Distance is one of the most important factors and it is also most objective one because the unity of Haneul and Tang does not include Saram(Man). The distance in Taekwondo changes continuously and it is alive. Everything that changes and, everything that lives has its rhythm in itself, so when you and your opponent face and move in a particular distance two rhythms also meet each other making one controlled in that distance. This control is the true rhythm of TAEKWONDO. It can be in you or out of you.

The relation of distance and rhythm, it is simple and each of the both is included in the other. Thus it is one and an easy thing for Taekwondo man. To put you in a proper distance means to be able to move with a proper rhythm. Everything ideal is essentially simple, in which difficulty and easiness are same. Distance differs from rhythm delicately on it. This sort of rhythm can never be seen but rather can be found when you raise the vitality in yourself up and harmonize its rhythm with the world. Therefore you cannot find the distance of Taekwondo with your eyes yet you should find it with your mind. And you should do Taekwondo not with only your mind but with your whole.

What is distance for? The distance in Taekwondo is that of the offense and defense, that for the control over the opponent and the protection of yourself. This offense and defense constitutes the whole meaning of Taekwondo's motion, which realizes itself in distance on one hand and shows itself in poses on the other hand. Here, tide and balance when united makes pose.

Why do we discuss pose? For pose is visible so easy to correct in the course of training. The flowing rhythm turns to the equipped rhythm in pose. That is, when you make your pose its figure determines the width of rhythm possible for you. Owing to this reason, the opponent's pose tells you what his motion can be like. To say differently, you can see all possible motions in his pose. A good pose should not be merely a stable one but rather it itself should be one that oppresses him, which relies on the same reason. It must not be 'for the control over' him but 'controlling' him.

In this manner, the motion and the standstill are not different in Taekwondo, which has the same meaning as Saek Jeuk Si Gong and Gong Jeuk Si Saek(, )⁴⁾ the Buddhism teaches us. You know that everything visible is empty because you see it not with your eyes but with your mind. In the same manner, you can see the motion hidden in your opponent's pose when you look into his mind over those temptation of his visible figures. Rhythm flows along the changes and motions. The rhythm that manages all motions is extended even to the calm pose of Taekwondo like these.
