In our materialistic and skeptical age, it can be difficult to take seriously the existence of real spiritual beings. Nevertheless, countless individuals -- from the historic founders of religions to those who have been through near-death experiences -- have spoken of beings of Light, such as Angels and Archangels, and 'evil' beings, spirits of darkness.The author, basing his work on Rudolf Steiner's teachings, presents an epic picture of the forces of 'good' and 'evil' -- a battle of cosmic dimensions in which we are all intimately involved. He clarifies the pivotal role of the Archangel Michael, the 'Guardian of Cosmic Intelligence, ' who fights to hold the balance between the key powers of evil in our time -- Lucifer and Ahriman -- and describes other members of the evil hierarchies. He also discusses the biblical Apocalypse of St. John, the Mexican Mysteries, and much else.This book is an essential guide to meeting the challenge of evil at the new millennium.
