Attacking the opponent with all of his on one hand, Taekwondo man, when he copes with the opponent's attack, should control himself with his fullness and receive it with his emptyness, having both fullness and emptyness in oneness. It is on the same grounds of that a drum receives hitting of a drumstick to its sound, and a drum, changing the hitting to sounds, can remain as a drum not broken yet realized as what it is because its inside is fully empty. This emptyness is also a fullness at once, and this produces the harmony of a drum that it receives the hitting of a drumstick to its majestic sound.

Fullness is that something can be produces from its inside while emptyness is that it can accept and hold something. The fullness commented in Taekwondo's attack refers to that your preparation for your opponent is so sound as to produce the superior control over him while the emptyness refers to that his preparation for you is as disadvantageous that you can accept and hold his defective motion.

Thus, the Taekwondo man, who receives the opponent's attack, moves all of himself aside playing together with him like the water that steps aside ways of an oar. Therefore, you stand aside close to the opponent's attack and the remnant parts, which couldn't move aside yet, prevents him like the water wave that holds the oar, and this also can be a good attack. Accordingly, the opponent's attack cannot hit the center of Taekwondo man and fails and comes to fight with the world because of the Taekwondo man's moving aside. This is possible because Taekwondo man moves his whole body at once and thus avoids the sharp attack of the opponent with his smallest motion.

Since you avoid only the sharpest attacks of the opponent you can stand all the way close to him, and thus can hit him at every proper time when you see good chances. Because the water, which moves aside the ways of the moving oar, can follow and strike the oar as soon as it passes by because the water never get far away from the oar. And because the Taekwondo man avoids only the sharp parts of the attack yet accepts and holds its soft aspects at once he never get destroyed in spite of the opponent's attack, of which the whole is due to that the opponent alsways attacks the emptyness of the Taekwondo man.

This sort of motions of Taekwondo are those of moving your center to the most proper position through the movement of your whole body also when you've attacked as well as when you attack. This is to move the whole body of from the finger tips to the feet toes in oneness. Therefore, although the motion were slow and small it becomes quick and big, and since it is quick and big it can receive big power and shock. The water wave can prevent a ship strongly from going forward not because much quantity of water strikes against the ships' direction but because the whole water should move even when te ship plows throught the waves only a little. This is the reason why the foot opponent cannot catch me and why the weak I can stand my strong opponent.

All of these mean a thing, that the best way to avoid and defend the opponent's attack is not to get far away from it, but rather to enter its inside, thus to pierce the opponent and keep yourself in him, and thus to hold the opponent in you. Every attack is to be made of the motions of huddling oneself up and spreading out, and its common man's motion to draw himself back far away from the attacker when the attacker huddles himself up or spreads out his body, while TAEKWONDO teaches you to pierce the attacker with no excrescence and to hide yourself in the scattered place in him. This is same as the basic attitude of Taekwondo in life that pursues the most positive life.
