I. Occult Science and Occult Development

Through his human faculties man strives for occult knowledge and may also acquire it, but occult knowledge has a greater significance for the world than it has merely within the human soul. In the world around us we can distinguish different substances and materials through which its various phenomena and manifestations are given expression. In the Primal Principle, the essential nature of which can hardly be expressed in words of human language, all creatures, all things of the earth and all worlds are rooted. But the individual differentiations of this Primal Principle come to expression in the physical world in the substances of earth, of water, of air, of fire, of ether, and so forth.
