Robert Powell, explores what 2012 really means, updating the research presented in his timely and ground-breaking book Christ & the Maya Calendar (coauthored with Kevin Dann). In this new book, Powell focuses on two important and significant prophecies by Rudolf Steiner. The first (from 1909) concerns the Second Coming of Christ, his appearance to humanity as the Etheric Christ. The second prophecy (from 1919) represents the shadow side of Christ¿s Second Coming. It concerns the incarnation in human form of the being known as Ahriman (ancient Persian tradition) or Satan (Judeo-Christian tradition). In this connection, the Christian tradition also speaks of the coming of the Antichrist (as clarified in the book, the term Antichrist, as used by Steiner, has a specific meaning and does not signify the incarnation of Ahriman).
