Tarot cards mirror the Soul. They reveal your subconscious needs and wants. In some cases, you already know the answer to your question or the reason for your situation but it is placed firmly in the back of your mind and your conscious self can't (or won't) access it. Tarot allows you to bring it to the fore. When you see it in writing or hear it said out loud you are better able to consciously deal with the situation.
