EXCELLENT QUESTION! The "yin-yang" symbol of Eastern religions represents the fact that the universe is based on complementary opposites, such as good/evil, hot/cold, light/dark, up/down, day/night, and, believe it or not, male/female.
Violating the yin-yang principle with absurd notions like "homosexual marriage" is to dent the very fabric and foundation of existence itself, and risks calling down destruction on ones self and those nearby.
"used to describe how seemingly distinct or opposing forces are interconnected and interdependent in the natural world, giving rise to each other in turn" http://en.wikipedia.org/wiki/Yin_and_yang
Without one, the other cannot exist. Good/Evil, Light/Dark.
Balance and Harmony
Why the dot of opposing color, then? It was explained to me many years ago that it symbolized that there is nothing pure in this world. No true pure evil or true pure good. A bit of feminine in men and a bit of masculine in women.
what is the taoism's sign (the half black half white circle one) meaning?
