If we now pass to the mineral kingdom we find in the forms of crystals something that directs us into space far beyond our solar system. In the formative forces of the mineral kingdom we find forces which reach far beyond the solar system. We are led, especially when considering those forms of the mineral kingdom through which the light passes, to a perception of what takes place far beyond our solar system.

It has a universal existence; the higher the being the more it is suited to the system of our earth and sun.
