I do not need scientific prove, I get all the prove I need from my own experience and from what I see and hear from my students. Sometimes it does seem miraculous - but I also admit, not everbody has that experience. Not everybody has the patience and discipline to pull it through until they get an effect. Meditation is work, which I consider worthwhile for myself.
Chopra is not synonymous with meditation for me. All those philosophies are not needed if you practice it regularely.
Oh, and I am a great friend of the placebo effect - isn't it wonderful that believe can effect such a change and even without the negative side-effects.
If you really want prove about meditation, there is only one way - do-it-yourself. Noone can prove it to you, it is something you have to experience yourself and you might end up dismissing it. Thats fine too. :-)
Oh, and I also like the placebo effect, although I have some ethical qualms about employing it in medical practise (since it would involve lying to your patients by claiming that you're giving them medicine when in fact you're giving them placebo). And if I get cancer, I'll go with the chemo rather than the homeopathic remedies magic water...
