Ahriman is a significant figure of Persian mythology. Rudolf Steiner, however, spoke of Ahriman as an actual, living spiritual entity. This being, he said, works to embed human beings firmly into their physicality, thus encouraging dull, materialistic attitudes and a coarse, dry intellect. In these extraordinary lectures, Steiner assumes a rare prophetic mode. He talks about an actual incarnation of Ahriman on Earth and the potential consequences of this event. Just as Christ incarnated in a physical body, so would Ahriman incarnate in the Western world?before ?a part? of the third millennium has passed.
