"You will then readily understand, that the heavy material to which surface-bred mortals allude as probably constituting the interior of the earth, is, in fact, nothing but the manifestation of a matter-supporting force, as exemplified in the sphere of attractive energy, the seat of which we are soon to encounter on our journey. Likewise the mutual attraction of the heavenly bodies is not a property solely of their material part, but an expression in which both the force-spheres and the matter collected thereon take part. "Tell me more of the sphere in which gravitation is intensest." "Of that you are yet to judge," he replied. "When we come to a state of rest in the stratum of greater gravity, we will then traverse this crevice in the sheet of energy until we reach the edge of the earth crust, after which we will ascend towards the interior of the earth, until we reach the inner crust, which is, as before explained, a surface of matter that lies conformably with the external crust of the earth, and which is the interior surface of the solid part of the earth. There is a concave world beneath the outer convex world." "I can not comprehend you. You speak of continuing our journey towards the center of the earth, and at the same time you say that after leaving the Median Circle, we will then ascend, which seems contradictory." "I have endeavored to show you that matter is resting in or on a central sphere of energy, which attracts solid bodies towards its central plane. From this fundamental and permanent seat of gravity we may regard our progress as up-hill, whether we proceed towards the hollow center or towards the outer surface of the globe. If a stick weighted on one end is floated upright in water, an insect on the top of the stick above the water will fall to the surface of the liquid, and yet the same insect will rise to the surface of the water if liberated beneath the water at the bottom of the stick. This comparison is not precisely applicable to our present position, for there is no change in medium here, but it may serve as an aid to thought and may indicate to you that which I wish to convey when I say 'we ascend' in both directions as we pull against Gravity. The terms up and down are not absolute, but relative."
