Spiritualism is a social religious movement popular in the nineteenth and early twentieth centuries, according to which an individual's awareness persists after death and may be contacted by the living. The afterlife, or the "spirit world", is seen by spiritualists not as a static place, but as one in which spirits continue to interact and evolve. These two beliefs—that contact with spirits is possible, and that spirits are more advanced than humans—lead spiritualists to the belief that spirits are capable of advising the living on moral and ethical issues and the nature of God. Some spiritualists follow "spirit guides"—specific spirits relied upon for spiritual direction.
