The Spiritual Hierarchies
GA 110
Ten Lectures by Rudolf Steiner given in Düsseldorf during April 1909 published in German as: Geistige Hierarchien und Ihre Widerspiegelung in der Physischen Welt. Tierkreis, Planeten, Kosmos.
These lectures take us into the exalted regions of the spiritual world, illuminating the actions of the spiritual beings in the kingdoms of nature and in the planetary and zodiacal spheres, and explaining the task allotted to humanity in the continuous evolution of this hierarchical world.
