There are none so ignorant as those who will not learn. So the few who will must do the thinking for the many who will not learn these truthful lessons. Mentality is one of the different densities, and like heat, light, electricity and sound is made up of elements that exist everywhere in Space. Mentality is a substance and its elements are made cohesive by the power of Suction and are made distributive by the power of Pressure. Mental manifestation like the manifestation of heat, light, electricity and sound is caused by concentration and pressure of matter.
Suction draws greater density toward it causing mass and solidification of matter.
Thus, solid matter contains substances that are composed of various elements. Pressure exerted upon solid matter squeezes the different elements out of it and causes them to fly away to different lodging places. Your room is flooded with light which comes through a bulb. The light is of a lesser density than the air that you breathe and illuminates it so that you may see objects about you. Passing from the bulb is a wire connecting with a machine that grinds from a lump of solid matter under pressure substances of various densities and these substances are drawn into your room by Suction located in the bulb.
