The psychic is taking the place of the priests and ministers of earlier years. Television programs turn to psychic for help in anything paranormal or strange. If one has a spirit haunting a house, who is the first person you would call. You surely wouldn't call the church, they would laugh at you. But their is a new professional that will take you seriously - the psychic.
Ministers are disregard as unable to help in such modern spiritual problems.
So they are helpless before real spiritual forces. They are disregarded as relics of a past religion that simply could not adapt to real world problems and mysteries. In other words, a psychic is someone who is in contact with the spirit world. Not only is a psychic in contact with the spirit world, but he also derives his powers from this world. It refers to a conjurer or spiritist.
