I think I didn't word my thoughts clearly. I was thinking that, because I believe the Universe doesn't want to make you a liar, (superstition on my part, I guess) you are predicting your future with Tarot or any other method shows you a particular future and could place limits on what is really best for you since what's best continually changes. I suppose Tarot or the i-Ching could take those changing futures into account, though, and thus be accurate. I unfairly lumped Tarot in with the Quija board and dark witchcraft, which makes me think of demons rather than Wiccans.
