“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. Man’s three bodies are symbolized by an upright triangle; his threefold spiritual nature by an inverted triangle. These two triangles, when united in the form of a six-pointed star, were called by the Jews “the Star of David,” “the Signet of Solomon,” and are more commonly known today as “the Star of Zion.” These triangles symbolize the spiritual and material universes linked together in the constitution of the human creature, who partakes of both Nature and Divinity. Man’s animal nature partakes of the earth; his divine nature of the heavens; his human nature of the mediator.”
