Written in the years right after World War II, this brief book offers a powerful meditation on evil and its eventual transformation. Focusing on the realm of “subnature,” or “the subterranean spheres,” von Gleich shows how the various layers of the Earth’s interior are linked directly to the mystery of evil. - The author begins by summarizing the classical image of the underworld of Greek mythology. He then describes the various qualities of the Earth’s nine layers, as elucidated by Rudolf Steiner. Finally, he outlines the counter-impulses—the forces of “good”—that work in opposition to the nine currents of evil harbored within the Earth. - Although written more than fifty years ago, von Gleich’s thoughts are more relevant than ever today, when humanity is surrounded by war, violence, starvation, greed, and the phenomena of increasingly obtrusive technology. - In a newly written introduction, Paul V. O’Leary places von Gleich’s work within the context of today’s world.
