Moving a bit of conversation from the other thread--
By tradition, I mean there are major traditions of Wicca--primarily the Garderian or Alexandrian, though many are Ecclectic, which is where I'm guessing you'd probably be.
Wiki has a pretty good entry on Wicca--good reading, if nothing else.
Wicca - Wikipedia, the free encyclopedia
I don't have access to some of my books right now, but I will try to get you a list of recommended reading at some point.
Wicca is generally unaccepted because if you get more than 10 of us together, we can't agree on much. Every pagan I've ever met pretty much laughingly agrees with that.
If you can, I suggest you train with a Wiccan priestess in your area--even if you don't STAY in a Circle/coven, it's really better to have trained with those who have been in larger Circles, then take what you want/need from that tradition and go forward as a solitary.
I was solitary for 10 years, and I've learned more in the last year by training with an older Witch than I did in the 10 years doing it on my own.
As for crystal healing--I believe in it, though I am not a healer. I'm more of a seeker, myself. Your best bet is to just start learning the metaphysical traits of ALL stones.
