ASTRAL LIGHT
Text: The same as the Archæus. A universal and living ethereal element, still more ethereal and highly organized then the A'kasa. The former is universal, the latter only cosmic viz., pertaining to our solar system. It is at the same time an element and a power, containng the character of all things. It is the storehouse of memory for the great world (the Macrocosm), whose contents may become reimbodied and reincarnated in objective forms; it is the storehouse of memory of the little world, the microcosm of man, from which he may recollect past events. It exists uniformly throughout the interplanetary spaces, yet it is more dense and more active around certain objects on account of their molecular activity, especially around the brain and spinal cord of human beings, which are surrounded by it as by an aura of light. It is this aura around the nerve cells and nerve tubes by which a man is enabled to catch impressions made upon the astral aura of the cosmos, and thereby to "read in the Astral Light." It forms the medium for the transmission of thought, and without such a medium no thought could be transferred to a distance. It may be seen by the clairvoyant, and as each person has an astral aura of his own, a person's character may be read in his Astral Light by those who are able to see it. In the case of a child who has not yet generated any special characteristics that emanating aura is milk white; but in the adult there is always upon this fundamental color another one, such as blue, green, yellow, red, dark-red, and even black. Every living nerve has its astral aura, every mineral, every plant or animal, and everything of life, and the glorified body of the spirit is made to shine by its light.
