I think you've probably all heard of the way in which some people are interpreting quantum physics to mean that we're all free to create our own reality? Or as our friends at Theosophy Watch put it: Does mind over matter? Weirdly enough - that's not at all a viable conclusion from the standpoint of quantum physics. There are definite limits to the freedom of an electron for instance. This implies that quantum healing too has limits: it's limited to the actual possible outcomes of the state one starts in.
