Thirteenth Lecture
But now a different era was to begin. As long as human beings were guided by blood, so to speak, they could not take their destiny into their own hands in the way that has been suggested several times. For this it was necessary that the service of these Ahrimanic spirits, as it was, be eliminated from the spiritual world. These spirits initially wanted to continue their activity of dividing people according to blood from the spiritual world; but humanity was to be driven to a more general conception of its entire spirit. What is often said in our field, that humanity is to be understood as a whole on earth, is truly not a cliché, but a modern necessity. And this is based on the fact that a strong, intense struggle has taken place between the Michaelic spirits and the spirits of Ahrimanic nature, which in the past differentiated people according to blood.
