I have a deck of Tarot cards (The Cat People, imagine that) that I use in situations where I'm facing a difficult decison and find it hard to make up my mind. I've found that laying out the cards (or even pulling one randomly out of the deck) and reading the definitions given in the handbook help me clear up what I'm unsure about. It's all intuitive, and I've found that what definiton causes the strongest reaction or gives me that "gut" feeling often has to do with the answer to the problem I'm trying to resolve. I've never read for anyone else, and probably never will. But, I've found that it's given me a form of communication with my subconcious mind.
