As far as the possibly of beliefs controlling our biology, I would suggest reading Dr Bruce Lipton's - The Biology of Belief.
There is a whole new field of Biology emerging called Epigenetics. And it is directly related to our beliefs.
Tons of articles and Youtube videos are available on the net.
It just so happens, the topic of my blog is beliefs. Good as place as any to start.
"If you can believe, all things are possible"
