"What the sun is to the solar system, the spirit is to the bodies of man; for his natures, organs, and functions are as planets surrounding the central life, (or sun), and living upon its emanations. The solar power in man is divided into three parts, which are termed the threefold human spirit of man. All three of these spiritual natures are said to be radiant and transcendent; united, they form the Divinity in man. Man's threefold lower nature - consisting of his physical organism, his emotional nature, and his mental faculties - reflects the light of his threefold Divinity and bears witness of It in the physical world."
