Tarot readings are one of my favorite types of divination. If you have never had a reading because you thought your reader was going to tell something bad, Well chances are you already knew what they would tell you.
Confussed yet, Tarot unlocks the sub-consious. It opens the door for your thoughts and desires to flow through. Readings should not make you uncomfortable but rather relaxed. They should allow you to let go and unwind for 30 minutes or so.
