It is more than the power that "pulls things to the earth," as the average man would define it. It does more than cause water to run down hill, and turn mill-wheels to drive machinery. Water-power results from Gravitation, but even the Energy of Niagara Falls is insignificant when compared to the other manifestations of the Mother of Energy--Gravitation. Webster defines Gravitation as: "That attraction or force by which all bodies or particles in the universe tend toward each other." Following that definition, let us add that: _Every particle of Substance has an attraction for every other particle_. In view of our belief that this "attraction" is a form of mental effort, let us regard the term "Attraction" as being a form of what we call "Desire," or even "Love," in the mental world. If you will think of it in this way, you will be better able to fall in with our lines of thought. And, in addition to every particle of Substance having an attraction (love or desire) for every other particle, _it has the means and power to draw that other particle toward itself, and to move toward that other particle at the same time_. Webster gives a very clear idea of this when he defines Attraction as: "_An invisible power in a body by which it draws anything to itself; the power in nature acting mutually between bodies, or ultimate particles, tending to draw them together, or to produce their cohesion or combination, and conversely resisting separation_." The majority of persons, when thinking of "Gravitation," are satisfied with the idea that it is a power that "pulls things down to the ground," and do not think of it as a force that "pulls things" other ways besides "down," and which is possessed and exercised by the speck of dust as well as by the whole earth--by the molecule as well as by the mass. The reason of this is that this power is so slight in small bodies of Substance that it is unnoticed; and that only when the mass is sufficiently large to make the "pull" strong does one perceive and appreciate that the force exists. The lack of information on the part of the average person regarding this subject is amazing, particularly when the importance of the knowledge is understood. The attraction that holds the molecules of Substance together is Gravitation. The attraction that "pulls" a piece of Substance to the earth is Gravitation. The attraction that keeps the suns and planets in their orbits is Gravitation. Let us see the operations of the Law.
