The Occult Anatomy of Man by Manly P. Hall (1929) explores the human body as a microcosm of the cosmos, interpreting anatomical structures—such as the brain, heart, and spine—through the lens of ancient mysticism, Hermeticism, and esoteric philosophy. Hall explains that physical anatomy reflects divine principles, where bodily functions are symbolic representations of spiritual and mental growth. The work serves as a guide for understanding the hidden spiritual dimensions of human physiology, encouraging a blend of scientific awareness with mystical insight.
