Religiously Speaking ... My premise: Alchemy, Positive-Thinkers, Witchcraft are all the same?Do u agree?

You have some rather broad categories there, and I suspect there are some witches who will take issue. Nevertheless, I agree with the basic idea. I don't grant credibility where it is not due, mind you. But the idea that one can make things manifest via will seems to be in common, depending on the specific schools of thought you are comparing.
