Yang-Yin Symbol

Take a look at it sometime, a close look. Often when I present some philosophical meanderings I refer to three, heave-man-earth, etc. but is there a "third" part of the symbol?

You have the "white half" then the "black half" and then the "two smaller white and black" within the other white and black halfs. It is referred to as the Yang-Yin symbol with only two descriptive words, "yang and yin." So, is there a third?

Yes, there is. I can think of two right off the top of my head. Yang (obvious), Yin (again, obvious) and void (not so obvious). How is void symbolized in the symbol? Ever notice that the majority of the symbols are enclosed in a black line that forms a circle? The circle denotes a few things but it is a "third part" of the symbol.

If yang-n-yin balance out it becomes the full circle but as nature, universe, intended the smaller white and black in the yang and yin fields are a seed that give birth to the next cycle keeping the cycles, rhythms and patterns constantly generating new birth-life-death of the myriad things of the great Tai Chi, the one.
