George,
Here is one definition of zero from a book I just received. It says, regarding the zero, when it presents itself in a seemingly coincidental manner, its message may be one of great significance.
"Zero, by definition, equals nothing, and yet it encompasses the promise of everything. Even though zero is not technically a number, it represents the "number" of the "absolute." It is a powerful force and indicates the principle of great transformation and spiritual change. It represents both the unplanned and the unknowable. Because its symbol has no beginning and no end, it fittingly signifies both beginnings and endings as well as being in the moment. While it seems to stand for a lack of substance, it is actually indicative of boundless, unlimited potential. Zero can suggest either great knowledge or a lack of knowledge. It is the symbol of dichotomy, the ellipse of its two sides, signifying both rise and fall, evolution and involution."

So, there you have it.
