Astral Light This is the next cosmic plane above the physical, which is to the physical globes of our earth or of the other bodies of our solar system what the linga-sarira is to the human physical body. As such, it is the carrier of life-forces -- jiva cosmically, and prana individually -- and the storehouse of cosmic energies on their way to or from physical manifestation. It preserves an indelible record of all events on the astral and physical planes, there being continual interaction between the two planes. No natural phenomenon, whether mental, psychic, or physical, can be explained without it; without it, the physical world would crumble to impalpable dust.
The astral light is itself divided into subordinate planes; the lower regions teem with gross emanations from the earth, including psychic remnants from deceased beings, which exert a negative influence on the living, especially when intercourse with these remnants is encouraged by moral and physical weakness or by ignorant experiments.
The alchemical action of the astral light and its intimate connection with the physical sphere explains epidemics, whether physical or psychological. Because it transmits thoughts and emotions, its connection with karma is evident. The astral light is the mother of the physical world, just as akasa is the mother of the astral light.
The astral light is virtually the same as the sidereal light of Paracelsus and other medieval mystic philosophers who followed him. The reason for calling this kosmic plane astral or sidereal is that all nature being a vast and intricately interwoven organism, the stars and planets emanate into each other their respective celestial energies and substances. Thus, because there is this constant interchange of starry fluids emanating from the different celestial bodies, the term astral light has a foundation of esoteric scientific fact. It is applied specifically to the second kosmic plane only because it is nearest to the physical and beings living on the physical plane at times become sensible of the existence of the second kosmic plane by means of flashes of starry light or sensations of luminosity. Hence the ancient initiates, knowing the source of this starry substance, properly called it the astral or sidereal light, or by some similar expression. The astral light, finally, is the very dregs of akasa, and is virtually the same as the hypothetical ether of science.
