Tarot Cards: I have never seen a deck in my life. Things like tarot cards, fortune telling, crystals, Ouiji (sp?) boards, hypnotism, and yoga were forbidden because they are demonic. Of course, I don't believe that anymore and think they would be pretty harmless. Unless you got a bad fortune and made it a self fulfilling prophecy.
We have a new agey bookstore here which sells those types of things but I've never set foot into it. I've always been interested in what was inside and told DH I'd like to check it out now. :)
