Mediums are people who are able to access information presumed to be from the afterlife. The objective of mediumship is to prove survival of the human personality after death, and to help the bereaved come to terms with their loss. Mediumship is an experimental process - no results are certain.
Mediumship has gained a bad reputation among the general public due to the number of fraudulent mediums working at one time. Scientific investigation of mediumship, common in the late nineteenth century, has been greatly reduced. Modern-day researchers tend to concentrate on the study of Near-death experiences (NDEs).
A Physical medium is one who brings about the manipulation of objects by unseen forces during a sitting.
Mediums are often called Spiritualists, although they do not necessarily belong to that church. Other faiths such as Brazil's spiritismo, or Louisiana Voodoo, also have their mediums.
