2-2-2. Samjae and Change

This Ilgiyae has no specified form. So it is not even oneness. Therefore it has been said "principle begins where is not even one."¹⁾ But it includes every skill. Therefore it has been said "body builds numerous beings."²⁾ Thus Samjae is fundamental frame of changes of yin/yang, and also of techniques of Kang-Yu.

Let us examine along the logic of <Yeok> how Ilgiyae becomes the foundational framework of Kang-Yu techniques through Samjae.

<Hankeul, the Korean letter system was invented based on Samjae>

It was said in The Great Appendix; “The movements which take place in the six places (of the hexagram) show the way of the three extremes (i.e. of the three Powers in their perfect operation)."³⁾ Here, ‘the three extremes’ refers to just Samjae.⁴⁾ By the way, “Each embraces Samjae; and, being repeated, its full form consisted of six lines builds a hexagram. A distinction was made of to the yin and yang lines, which were variously occupied, now by the strong(Kang) and now by the weak(Yu) forms, and thus the figure (of each hexagram) was completed.”⁵⁾ It means, a hexagram is a coupled two trigrams and a trigram is composed of three yin/yangs along the way of Samjae.

Considering them conversely, various changes are symbolized by hexagrams in I Ching and each hexagram is composed of two trigrams coupled. A trigram is made of accumulation of three yin/yangs, where three yin/yangs are accumulated by each owing to yin/yang's following the framework of Samjae. “Accordingly, the movements which take place in the six places (of the hexagram) show the ways of three: heaven, earth and man.”⁶⁾

On the other hand, these trigrams symbolize not only changes of Kang-Yu techniques in Taekwondo, but also of everything. Because yin/yang represents everything distinguishable while Samjae is in its meaning the framework along which everything that there is changes. Everything distinguishable, following the framework of change, can represent every change in the distinctive manner. This is what the trigrams mean. From this point of view, since trigrams are founded on Samjae and hexagrams of I Ching is composed of the trigrams we can say that the entire I Ching is founded on Samjae.⁷⁾

7) By the way, no one in the whole realm of Chinese philosophy discuss this Samjae systematically, which though is the essence of the philosophy of I Ching. Of course nothing in that of India or Japan. You can find the systematic discussion about it only the Korean bibliography like "Cheon By Kyeong" and "Sam Il Sin Go", etc.
