Let us imagine the Cosmic Mind as a great body of Something filling Space, instead of as the surface of the Ocean, which figure we used just now--either figure is equally correct. This great Cosmic Mind is to be thought of as filling Space, and containing within its volume (Oh, for a better word!) countless worlds, and suns, as well as smaller bodies of Substance. These suns and world, and bodies are apparently free and unconnected, floating in this great volume of Mind. But they are not free and unconnected--they are linked together by a web of lines of Gravitation. Each body of Substance has a line reaching out in a continuous direction, and connecting it with another body. Each body has one of such lines connecting it with _each_ particular "other body." Consequently, each body has countless lines reaching out from it; some slender, and some thick,--the thickness depending upon the ratio of distances maintained by, and relative sizes of, the particular bodies that it connects. This system of "lines" form a great net-work of connections in the volume of Mind, crossing each other at countless points (but not interfering with each other.) And although the number may be said to be "countless," still these lines do not begin to cover the entire dimensions of Space, or of the Mind that fills it. There are great areas of Space entirely untouched by these lines. If one could see the system of lines, it probably would appear as a sheared off section of a great spider's web, with lines in all directions, but with "plenty of room" between the lines. _Perhaps these lines converge to a common centre, and that centre may be----!_ But this is transcendental dreaming--let us proceed with our consideration of the use of these lines. It is to be understood, of course, that these "lines" _are not material_ lines--not made of Substance--but rather, "conditions" in the Cosmic Mind. Not Thought-waves arising from the Excitement of Particles, but Something more basic, simpler, and more permanent. Let us look closer and we will see that the great lines of Gravitation radiating from, and connecting world with world--sun with planet--are really cables composed of much smaller lines, the finest strands of which are seen to emanate from each Corpuscle or Particle of Substance--the "line" of Gravitation reaching from the Earth to the Sun being composed of a mass of tiny strands which connect each Particle of one body with each Particle of the other. The last analysis shows us that _each Particle is connected with every other Particle in the Universe by a line of Attraction_. _These "Lines of Attraction" are what we call Gravitation_--purely Mental in nature--Lines of Mind-Principle in the great volume of mind.
