Gross man seldom or never realizes that his body is a kingdom, governed by Emperor Soul on the throne of the cranium, with subsidiary regents in the six spinal centers or spheres of consciousness. This theocracy extends over a throng of obedient subjects: twenty-seven thousand billion cells (endowed with sure if seemingly automatic intelligence by which they perform all duties of bodily growths, transformations, and dissolutions) and fifty million substratal thoughts, emotions, and variations of alternating phases in man’s consciousness in an average life of sixty years.
