-raises hand- It was always on the list of 'things to do', so a few months ago I picked up a deck and a few books. I remain a novice reader but I can sense the power they hold.
Not otherwordly power, I'm not talking about magic or being psychic. I use them as tools to pry open unturned rocks in my mind, or doors that refuse to open - or that I won't LET myself open. The first thing I say when doing a spread for someone is "Do not ask a question you don't want answered."
For example; one lady asked about what she should do in her situation. She was living with her ex-lover and had a new lover, but wanted to know if the tarot cards would tell her that it would be okay if she slept with both at the same time. You don't need a card with a picture on it to know that's not a good idea, but she was eager to fool herself into thinking it would be OK to do so if the cards suggested a favorable outcome. Often we know what action we should take, we just don't want to face up to it.
So my way of using the tarot is not particularly mystical, but I believe learning how to use it has been one of the best choices of my life.
On the other hand, it can get a bit scary when people want me to read for them. You can tell which ones truly, absolutely believe that 'possible outcome' that the cards suggest is carved in stone as if some divine being were giving them a summary of the future.
