Initiatic Science teaches that we live our lives immersed in the ocean of fluidic matter known as astral light. This fluid is so sensitive that it bears the record of everything that occurs in the universe: the most insignificant gesture, the slightest, most superficial emotion, every fleeting thought that goes on in our minds: it is all recorded. According to esoteric tradition, astral light is an extremely subtle substance emanated by all creatures, from human beings, animals and plants, to the rocks of the earth and even the stars in the heavens.”
