Making Little Movement Big Relyng on <Do>
"What are Kang-Yu"
"They are two aspects of Taekwondo technique.
Knowing Kang-Yu you can know every technique."
For such an offense you should be able to have both mind and body strengthened evenly, which brings you the reconciled power, and should be able to move all parts together in the most proper manner once you move. And after all, all movements when concentrated on a motion make a right motion of Taekwondo. An offense of hitting an opponent appears as a both peripheral and essential aspect of this moving all, and this offense is powerful and fierce.
For an example, when you hit the opponent with you fist
it should not be that only your fist moves striking him. Your foot should
kick the ground pushing your body, your body support your shoulder, the
shoulder push the arm, and the arm pierce him with your fist exploding in
his body. All the same in your kicking too. Your supporting foot should
push the ground when you lift the kicking foot and you move your body forward
while the supporting foot should keep the balance of sudden falling down
forward of your waste. Then the waste swings the lab and the lab swings
the calf to pierce his center with the foot tip.
Every movement of this whole process goes together with all the others at once, thus even though the motion needs only a little room its power can be so strong as that of your rushing from a long distance. Since the motion is in accord with the change of everything you can produce the power of heavy mountain even if you were light, and since the way of its movement includes spinning and returning in one its offending power is sharp and hard like the edge of a massive sword even if it moved slow and tender.
Your motion, no matter what it might be, comes from the change of <Heo-Sil>, which relies on the differences of Yin & Yang and Kang & Yu. So you can reconcile the differences of Yin & Yang with those of Kang & Yu in a harmonized motion replacing the small change of <Heo-Sil> with them, thus you can move like above. This is to replace the making big changes of <Heo-Sil> in a motion of long distance with the making big differences between strain and relax in muscles and bones, so that you can make up for the smallness and the lightness of your body with the bigness and heaviness of the earth on which you stand, and fill up for the slowness and the softness with the speediness of straight line and the hardness of spinning. The best way to master this motion is to control breath calmly with arranged mind. This above is called making little movement big relying on <Do>. How can it be possible that this sort of offense is sensed and defended by the opponent?
