When men and women willingly give over their minds and bodies to spirit entities, and these spirits enter and control them, using them to heal, or to give teachings and other information, this is called channeling. Crystal work uses crystals to invoke the spirits. The spirits claim they can assist people toward true individual, social, and spiritual enlightenment. Channeled spirits claim to be wise and loving entities, but are they? What is their real purpose? The authors examine the potential problems and dangers that can occur through channeling, along with a biblical evaluation of the practice.
