When Water changes into Wind
Yin-yang, yang-yang and yin-yin
When trigram water changes into trigram wind, only the top line changes.
In a trigram change, the second trigram goes after or below the first, especially if you write them like they did in China, top to bottom on narrow bamboo slips.
The second trigram is what you hope for the future, this is what your intention and/or fate bring about. It is called ‘zhen’, oracle-answer (in Wilhelm ‘perseverance’) Hexagrams are stacked trigrams. We all know, but many don’t think they are originally made like that. Every line from the first becomes the same line in the second.
And then you put them on top of each other. Some lines have changed, other lines are unchanging.
The hexagram is the story: the bottom line (muddy well) becomes line 4 (masonry lined), the second (a gully) becomes 5, a cold spring, the 3d line, an unused wel, becomes the top line, a well that collects water for everyone. The explanation for the change Kan-Xun, Wind below Water, line 3, says “The king is bright, together we receive its (or his) blessing”: line 3 changes from yin, which does the work, to line 6, bright emitting yang: the well is gathering.
I don’t know if it is clearly visible in all hexagrams, but this one is a beauty.
What I already noticed, is that lines 1-4, 2-5 and 3-6 are each two sides of one meaning, but the ‘bright’ king (yin changing to yang) made it extra bright to me.
