I understand this thread is a little old and the original poster probably doesn't refer back to it anymore. If by chance Robert does. Then I would very much like to pose this.
I too, have a very analytical mind, which rarely rests and you're looking for proof that all this works to maybe rest your own mind. It's probably not going to help you very much, because you'll end up questioning another aspect about it.
The system is based on belief and that you have an innate ability to heal yourself. Which if you refer to 'epigenetics' you have a whole field full of research outlining that this is true.
Dr Bruce Lipton has a book devoted to his days in biology and finding how our cells interact with the environment.
It's call the biology of belief.
Or you can just read up on epigenetics at a site called
www.whatisepigenetics.comWhich has both articles on how it works and how it effects you.
Or you could also look into 'dark dna' which is dna that scientists believe are hidden within our system and they're unsure of what it does.
The placebo effect has been known for many years. There is even a website / database you can go to and read through all the sickness / diseases documented by doctors and reported with medical journals to back up the proof of this.
Its called the spontaneous remissions project.[url]

But then if you doubt further from there, you'll probably start heading down the road of Quantum physics (why not go down the road of how everything is the way it is right?)
This is where the road will probably end as the debates still rage on between scientists who get pinned as psuedo scientists because they believe in consciousness that formed matter and the physicists who believe matter formed consciousness and arrive at the end of the theory which comes down to probability. Leaving you living in the unknown anyway.
Unfortunately at the end of the day, there are 'materialist' that believe everything was formed from matter and from one big bang a miracle formed and there we are. To the psuedo scientists that believe energy and consciousness created what we are today.
Personally I believe the quantum physics theroy is still unfinished. But that's a different dicussion.
Physics will push for matter, but consciouness never comes into their equations, nor do they have an equation for consciouness. There is no answer. Just belief.
You can submit yourself to the work and try it see how powerful your mind is, or decide against it and go the route of MDs and try and change your situation with matter effecting matter.
If you want further proof, go to one of the weekends. You can gain access by paying a little extra to your own results, see the brain scans, see which genes were up regulated and which were down regulated.
The point is, you'll never have an answer for certain, scientific facts are updated all the time, or left in tbe dark and never updated. Do some experiments of your own and just try the work. If it works. Then you have your proof.
