In The Cosmic Forces Of Mu, James Churchward extends his grand speculation about a vanished Pacific supercontinent into the realm of science and metaphysics. Drawing on what he presents as ancient tablets and priestly teachings from Mu, he outlines a universe governed by a single primal force, from which all secondary “atomic” forces derive. Chapter by chapter he moves through the origins of the great forces, the workings of the earth’s own energies, the structure of the atmosphere, and the action of rays and vibrations on matter and life. Throughout, he insists that the priest-scientists of Mu possessed a unified cosmology far in advance of modern knowledge.
The later chapters apply this cosmic framework to more specific phenomena: the nature of the life force, the specialization of species, the role of the sun in sustaining creation, and a grab-bag of “sundry phenomena” that range from weather and earthquakes to psychic impressions. Churchward’s narrative is part lecture, part revelation, and part polemic, frequently dismissing contemporary geology and physics while proposing alternative explanations rooted in Mu’s lost wisdom. The result is a classic of fringe occult nonfiction: a dense, diagram-laden tour of an imaginary ancient science that has influenced generations of readers interested in Lemuria, esoteric cosmology, and alternative histories of the earth.
