I have been to a Clairvoyant who knew things that she could not have possibly known about.

But she didn't, she fooled you into thinking she did, it's simple trickery, you can actually be taught how to do it should you be so inclined.

Stage magicians do amazing tricks but when you watch them you know they are going to try and fool you and no matter how amazing, you know it's trickery, however if you believed in magic you might think they had actually done something really magical.

Should you be prepared to believe in a clairvoyant, you won't see the trickery so go away thinking they really have come out with amazing revelations.
