Nature is a light, and by looking at Nature in her own light we will understand her. Visible Nature may be seen in her visible light; invisible Nature may become visible if we acquire the power to perceive her invisible light.
We do not know it because we are fooling away our time with outward and perishing things, and are asleep in regard to that which is real within ourself.
It is said that a wise man rules over the stars, but this does not mean that he rules over the influences which come from the stars in the sky. It means that he rules over the powers which exist in his own constitution.
