In this existence, we experience two phenomena, the physical or matter and the other, the mental or Consciousness. The brain being physical or matter and thoughts or mental activity being consciousness. I do not believe the physical is a creative force but that consciousness is. I do not believe the physical ever creates the non-physical or consciousness but that it is the other way around.
As I mentioned in an earlier post, thoughts flow from beyond. No one thinks before hand, next I will have the following thought. We have no idea what will be our next, nor can we stop the incessant flow.
The old physics taught that matter was the all important aspect of reality but along came quantum physics that stood those theories on their head. Now, science is coming to realize that matter does not even exist but that everything is a field of electrical energy that forms matter into infinite conglomerations of atomic particles united in various form and constant change. In reality only undivided Consciousness exists.
