" Light is not only sacred because it dispels the darkness in which lurk all the enemies of human life. It is also sacred because it is the vehicle of life. This is evidenced by the effect of sunlight upon plant, animal, and human life. Light is also the vehicle of color, the coloring matter of all earthly things being imparted from the sun. It is the vehicle of heat, and according to the wisdom of antiquity, it carries the sperm of all things from the sun. Through light also pass the impulses from the Grand Man. According to the Mysteries, God controls His universe by means of impulses of intelligence which He projects through streamers of visible or invisible light. This light serves the universe in a capacity somewhat similar to that in which the nervous system serves the body. "
