I like to look at things this way...
ONE separated to become separate.. just for the experience of 'itself' in a variety of different forms. Maybe this progression stems from the fact that we want to experience more and more variation of the whole. Also I could extend this theory to say that upon death we become ONE again. And also throughout our life we may be able to catch glimpses of this wholeness using various methods.
Hmmm.. I should find a more elegant way to express this.
Essentially.. its wholeness and duality.
Wholeness is the same as nothing and the same at everything all at the same time or all at no time.
Duality is the experience of this wholeness being separated into many different parts.
I'm glad that clears things up
