Demonic possession, exorcisms, Luciferic egotism, Satan worship, and obsession with evil seems to arise in the news everyday and yet there is little understanding of what the nature of those beings and forces are, or what their intent and mission is in relationship to the evolution of the human spirit. Dr. Rudolf Steiner tells us more about these issues than any other person in modern times. It behooves us to listen closely to his indications on these topics so that we might understand the biography of demons, devils, and fallen angels.
