Light, however, is something proceeding from the Sun, radiating in every direction. When it reaches the Earth it is attenuated through ninety million miles, the distance between Sun and Earth. How much it is attenuated we can scarcely conceive, yet we can see things from, in, and because of light, but cannot see light itself. It is so attenuated that we cannot see it, but there is enough of it that we can see to read by it. The light of the Sun must be diametrically opposed to material substance.
Material substance is drawn into the Sun, light is thrown out from the Sun.
It, then, must operate by opposite laws to those that affect material substance. The Sun ceased to be material substance when transformed into light and hurled outward to the planets. If light is thus attenuated through ninety million miles, it is so great an attenuation that we can scarcely think of any greater, yet it was a simple substance at the beginning. There is always a tendency to influx where simple substance is active. When there is a disturbance in the inner planes of man's economy there is an influx, from the atmosphere, of some deleterious simple substance.
