To speak of ethers as an avenue of forces conveys no meaning to the average mind, because force is invisible. But to an occult investigator the forces are not merely names such as steam, electricity, etc. He finds them to be intelligent beings of varying grades, both sub- and superhuman. What we call "laws of nature" are great intelligences which guide more elemental beings in accordance with certain rules designed to further their evolution. The old folk-stories are now regarded as superstitions, but as a matter of fact, one endowed with etheric vision may yet perceive the little gnomes building green chlorophyll into the leaves of plants and giving to flowers the multiplicity of delicate tints which delight our eyes.
