I have told you that the Event of the Mystery of Golgotha was a moment of supreme importance for the evolution of the world. The Christ appeared in the realm into which man enters after death, where Ahriman’s influence was even mightier than in the world around man here on earth between birth and death. In the realm of existence between death and rebirth, Ahriman’s influences worked upon man with terrible, overwhelming power. And if nothing else had taken place, utter darkness would gradually have closed in upon man in the ‘realm of Shades’ — as it was correctly designated by the ancient Greeks. A condition of complete isolation, leading to the intensification of egoism would have set in between death and rebirth; man would have been born into his new life as a gross and overweening egotist. Hence it is more than a figure of speech to say that after the Event of Golgotha, at the moment when the Blood flowed from the wounds, the Christ appeared in yonder world, in the realm of the Shades, and cast Ahriman into fetters.
