Avoiding Opponent's Offense With Oneness of Fullness and Emptiness
"What is Kang?"
"Concentrating my much force on a weak
point of my opponent; this principle is called Kang."
Offending your opponent with all of yours on one hand, you as a Taekwondo man, when coping with his offense, should control yourself with your fullness and should receive it with your emptiness, having both fullness and emptiness in one. It is on the same grounds of that a drum receives the stroke of a drumstick into its sound. The drum, changing stroke to sound, can remain as a drum not broken yet realized as what it is because its inside is fully empty. This emptiness is also a fullness at once, which produces the harmony of a drum so that it receives the stroke of a drumstick to its majestic sound.
Fullness is possibility to produce something from its inside while emptiness is that to accept and hold something. The fullness talked of in Taekwondo's offense refers to a state that your position against the opponent is so sound as to produce the superior control over him, while the emptiness refers to that his position against you is so disadvantageous that you can accept and hold his defective motion.
Thus, when you are the Taekwondo man who receives the opponent's offense, you move all of yourself aside playing together with him like water that steps aside ways of an oar. Therefore, you stand aside close to his attack with the remaining parts, which couldn't move aside yet, prevents him like the water wave that holds the oar, and this also can be a good offense. Accordingly, his offense cannot hit your center, so fails, and comes to fight with the world because of your moving aside. This is possible because you move your whole body at once, so you avoid his sharp offense with your smallest motion.
Since you avoid only the sharpest offense of your opponent you can stand all the way close to him, so you can hit him at every proper moment. Because water never gets far away from a paddling oar, no sooner does it pass by than water can follow and strike it, though water moves aside its ways. And because you as a Taekwondo man avoid only the sharp point accepting the soft aspect of the offense at once you never get destroyed in spite of the his powerful offense. All of these are possible due to that he always offends your emptiness.
In this way Taekwondo motion is to move your center to the most proper position through the movement of your whole body, not less when you've offended than when you offend, making one simple motion of the whole body from the finger tips to the feet toes. Therefore, although the motion were made slow and small it appears as quick and big, and since it is quick and big it can accept big power and shock. Water wave can prevent strongly a ship from going forward not because much quantity of water strikes against the ship's direction but because the whole water should move even when it plows through water only a little. This is the reason why the opponent cannot catch you though he hurried up and why you can stand his powerful offense though you were weak.
All of these mean a thing, namely, that the best way to avoid and defend the opponent's offense is not to get far away from it, but rather to enter its inside, thus to penetrate him keeping yourself in him, so as to hold him in you at once. Every offense is to be made of the motions of contracting and stretching. It is common man's motion to draw himself back far away from the offender when he gets ready to offend, while TAEKWONDO teaches you to pierce him without notice and to hide yourself in his scattered place. This is same figure as of the basic attitude of life in Taekwondo that pursues the most positive life.
