Question: What was  Achsa W. Sprague best known for?

Related documents: [0]  [DOC] Spiritualism is the belief that the spirits of the dead have both the ability and the inclination to communicate with 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 evolve. These two beliefs: that contact with spirits is possible, and that spirits are more advanced than humans, lead spiritualists to a third belief, that spirits are capable of providing useful knowledge about moral and ethical issues, as well as about the nature of God. Some spiritualists will speak of a concept which they refer to as "spirit guides"—specific spirits, often contacted, who are relied upon for spiritual guidance. Spiritism, a branch of spiritualism developed by Allan Kardec and today practiced mostly in Continental Europe and Latin America, especially in Brazil, emphasizes reincarnation. [END]
