No matter what you do with it, or no matter what you appear to do with it, it remains in one piece. 2 represents the complementarity of anything that isn't whole. Whenever you find a particular something you can be sure that its complentary part is somewhere to be found. There are always two sides of the coin. There is no object that can be examined without an observer existing at the same time.
Infinity represents the unlimited number of things can be found within a wholeness.
They are the facets of the hologram. None of these infinite things are the final truth about the wholeness, but that doesn't make them any less valid in their own right. Now, as to the reason for this whole arrangement. If we look at it metaphysically or religiously, we can regard the Zero as the eternal indestructible universal consciousness, the unlimited space that anything can take place in, the quality that remains unchanged no matter what goes on in it, the Prime Mover Unmoved. The One is the unbroken pervasiveness of this consciousness, the inherent integrity of it, no matter what takes place in it.
