Abstract
I have found the geometry of the mandala exists deep in the psyche as it appears in the Systema Munditotius mandala of C. G. Jung. In this article, I demonstrate the geometry of proportion, the Divine Proportion, the Golden Section, and the Extreme and Mean Ratio, which I have applied to Jung’s Systema Munditotius mandala published in The Red Book. I analyze Jung’s first mandala in its religious context and the philosophy of Immanuel Kant, an important influence on Jung’s psychology.
