Man, your logic is really screwed.
That is not the 'point' of Yin/Yang: Yin/Yang are principles developed to simply illustrate complementary relationships between what we see as opposites, as outlined in the Wiki piece I posted. IOW, the conditioned mind sees opposites as being in opposition, whereas the enlightened mind sees them as being complementary. It says nothing about absolute because that is not the 'point' of Yin/Yang. But at the very minimum, 'relative' automatically implies 'absolute', which, in this case, is the unity of Yin/Yang taken as a whole.
Again, your logic sux!
Where do you get the notion that 'absolute' means 'overpowering'? You haven't a clue. The Tao, for example, and what Yin/Yang is about, is an absolute, but specifically does NOT dominate.
Thuuuuck!
How do you come to that silly conclusion?
Wrong! The balance exists because of The Changeless!
"From the One, came the Two;
from the Two, came the Three;
and from the Three,
came the Ten Thousand Things"
Tao te Ching
The 'One' is The Absolute; the 'Two' is Yin/Yang.
Out of Nothingness, comes Everything, and that is The Absolute. Were it not so, there would remain something 'other' than Everything, which there isn't. IOW, there is nothing that exists relative to Everything, making it The Absolute.
Simple.
