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. They appear to know things beyond natural ability, such things as our love life, the future, the details of a crime, and more. There is no neutral parties in the spiritual realm. The psychic is in contact with demon forces.
Many psychics readily admit that they commune with a spirit beyond the physical.
They don't call them demons, of course, rather they are called spirit guides. But these spirit guides are nothing but demons. It is not only wrong to be a psychic, it is also wrong to consult one. It is morally wrong to call the psychic hot line, it is morally wrong to have your future told, it is morally wrong to call in a psychic for any reason. Consulting a psychic opens you up to demonic activity.
