does astrology work?

Nobody uses Tarot cards to tell the future. They don't work for that anyway. They're used as a psychological tool to access the user's subconscious or trends in their life through archetypal images, which can suggest new directions or options they may not have been aware of. So it's similar to psychoanalysis or counseling. The advantage of using cards is that the images are laid out in front of you and analyzing them can be easier than just listening to someone talk and trying to make connections that way.

Since each card has a standard interpretation, and its position in the layout is also significant, this gives structure to the reading while still allowing some latitude.
