I've recently discussed Bhuddism, karma, and the concept of Yin and Yang with some friends - and it made a lot of sense. There is always an opposite of everything, for non-existance, there is existance.
If there is an empty void, there is a universe full of matter. When there is up, there is down etc etc.
So based on that principal, would that explain how things exist without a creator?
But then the question becomes, what created this law? And if it even existed?
