God condemns fortunetelling of any kind. Plus, most of it is phoney anyway. Your friend already knows all about you, so it wasn't exactly difficult for her to tell you all about yourself, was it? She didn't need cards to tell her about your life.
Did you know that several years ago, when the welfare laws changed, the City of Brooklyn, NY was holding job training classes for people who were losing their welfare benefits and one of the classes was "How to earn a living as a psychic." The students were taught how to be a telephone psychic, and having psychic powers was not required for the course. They taught people how to listen to the caller, how to hear stresses and inflections in their voices that would give them clues to what the caller wanted to hear, plus how to use the internet to quickly find out information about the caller to help them "know" the person and "advise" the person.
There are oodles of ways a "psychic" can cheat and make you think they know all about you, but you are in fact telling them everything they can't find out on the internet.
Oh, and by the way, my dad's friend was killed by a psychic using a Oui-ja board to contact demons (the psychic called them friendly spirits, but how friendly were they when they carried out a murder?). The man's wife wanted to marry another man but she didn't want to get a divorce, she wan't her husband to die so she could keep the house and all their money, so she went to a psychic who helped her contact demons. They asked the demons to kill her husband, and at that same moment, her husband, a healthy athlete in his late 30's, had a massive heart attack and died at work. My dad was there when it happened and saw the man go from healthy to deadly pale and die right before his eyes. My dad went to the funeral where the widow admitted to him what she had done (she was very sorry she had done it) and my dad came home and threw out our oui-ja board, which we had considered a toy until then.
