7-10-1. Unification of Kang-Yu
Kang-gi and Yu-gi are complementary to each other. Therefore, it is neither
that Kang-gi surpasses Yu-gi always nor that Yu-gi always suppress down Kang-gi
for sure. Every technique always includes both Kang-gi and Yu-gi at once.
The hardness of Kang-gi is forcing a change as you intend to do against what
your opponent intends to do. Without any of this hardness nothing can be a technique
of Taekwondo, and furthermore, nor it can be intentional motion of man.1)
Therefore, without any of Kang-gi it cannot be a technique. On the other hand,
the softness of Yu-gi is following what your opponent intends to do. Without
any of this softness your motion cannot be efficient in the offense and defense
with him, just exhausting your strength only with conflicts to him, and after
all you will be broken as much as he is, and furthermore, if you face an opponent
of stronger muscles you will not be able to surpass him. Then, this cannot be
said to be a technique of Taekwondo at all either.
Therefore, Kang-gi includes softness and Yu-gi also includes hardness. On the
other, however, the hardness and the softness are merely main elements of Kang-gi
and Yu-gi, yet not all of them. Therefore, while each of the hardness and the
softness controls over the other in a change, it is not that any of both can
win the other fundamentally. Accordingly “No
matter how strong and hard your technique may be you cannot succeed in the attack
at the opponent without softness in it, and no matter how soft your technique
may be you should also have the hardness in it so as to catch and break his
Therefore it can be concluded that the slogan like “the-soft-capably-supress-down-the-hard(柔能制剛)”
doesn't reflect on the truth sufficiently. Instead, “the
soft capably suppress down the hard while the hard capably cut off the soft.”(Ch.
41) Only with both of Kang and Yu, we can say, it is the true Taekwondo.
