for a wile back in the eather of time i was part of a group that did cold reading / spirit reading.
this was certainly presented as spiritual and marketed as such.
we employed ever trick in the book to get the results and it was because it was so phoney that i left the group, this was early eighties when every one wanted to believe and every con artist in the would had
gifts.
i take the view that if you have faith in something then there will always be someone to take advantage of your faith for matterial gain off the top of my head, catholics, david blain, daren brown, fourtune tellers, and funeral directers.
as for changing your belife structure you do this through most of you life ie you belive in father christmas, mary popin's etc, then you grow up and belive in the almighty doller.
i belive that we are able to percive waves eminating from the brain but as yet don't have the knowledge to interpret them, thus we get impression's you know when your friend is ringing you.
that and the psygological tricks, body language etc alows me to be a better magician.
