By 1960 Christopher Hills had accumulated a large metaphysical library on frequent trips to Samuel Weiser Books in New York, while writing his own books, Kingdom of Desire, Power of the Doctrine and The Power of Increased Perception. At 30 he retired from business"The Business of Art" – Business Sketch Magazine, July 1961 and began to research multiple spiritual paths and the physics of what Albert Einstein called Unified field theory. Prolific research papers and lectures came out of Hills' laboratory in the Blue Mountains (Jamaica) on subjects such as bioenergetics, hypnosis, tele-thought, biophysics, effects of solar radiation on living organisms, resonant systems of ionosphere, and capacitor effects of human body on static electricity and electron discharge of the nervous system.
