Ahriman n.

A specific spiritual being who, in Rudolf Steiner's cosmology, presses human consciousness downward into hardened matter, mechanism, and pure abstract intellect.

Ahriman is, in Rudolf Steiner's anthroposophy, the specific spiritual being whose work is the downward materializing pole of human evolution. He is not a symbol or a personification of bad qualities. He is the actor behind the qualities the adjective ahrimanic describes. Steiner identifies him with the Angra Mainyu of Persian Zoroastrianism, extended into spiritual science as the being who will eventually incarnate in the West, just as Lucifer once incarnated in the East and Christ between them in Palestine.

Ahriman will incarnate in a human body in the Western World... This fact is predetermined in the evolution of the earth. The all-important fact is simply this: to keep the fact in mind, that we shall rightly prepare ourselves for it, for Ahriman will not begin to work only when he has incarnated in a human body; he is now preparing his appearance from the super-sensible world. He is already working from thence into the evolution of mankind. From that side he is seeking his tools through which he prepares for what must come.

Rudolf Steiner, Cosmic New Year (GA 195, lecture of 28 December 1919, Stuttgart)

Ahriman steps into Steiner's framework directly out of the Zoroastrian inheritance. In the Persian tradition reaching back to Zarathustra, Angra Mainyu names the destructive spirit set against Ahura Mazda, the wise lord of light. He is not metaphor and not a fallen angel in the later Hebraic sense. He is a coeternal counter-power, the being who introduces lie, decay, and hardening into a world otherwise streaming with the light of asha, the cosmic order. Steiner reads this old Persian intuition as a real spiritual perception, not a primitive dualism that later religions corrected.

His spiritual-scientific extension keeps the figure but specifies the work. Ahriman becomes the being whose task within evolution is to provide the resistance, the gravity, the cold clarity that any free human spirit needs in order to stand upright in matter. The danger is not Ahriman as such. The danger is sleep. When humanity stops noticing him, his gifts become his rule. He is already preparing his physical incarnation in the West, the same way Lucifer once stepped into a body in pre-historical China and Christ stepped into a body in Palestine. The honest task, Steiner says, is to recognize him fully and consciously, to use what he brings without being captured by it, and to keep the centre between his hardness and Lucifer's fire by holding to the Christ. The Ahrimanic Deception entry treats the specific lecture-cycle (GA 191, 1919) where Steiner names the deception by which Ahriman seeks to incarnate in a single human body in the third millennium. Ahriman works most intimately through the double, the shadow-being that attaches itself to each person shortly before birth and is bound up with the sub-earthly electrical forces. It is into the eighth sphere that Ahriman, together with Lucifer, seeks to divert the substance of evolution, tearing it loose from the lawful seven-membered cosmos. Ahriman is the second of the two beasts, the beast ascending from the earth. Ahriman works through the abstraction of money in the economy once it is severed from the real flow of goods. Ahrimanic forces are bound up with the comets and the cosmos that sweep through the planetary order. Ahriman stands behind Mephistopheles, the cold tempter who would chain Faust to the earth. Ahriman works as a historical force; see the luciferic and ahrimanic in history. The historical stream through which this cast entered modern science is Arabism.
