 sponge, very coarse and porous, of spherical shape,and completely fill every cell with fine sand, and also surround it entirely with sand; if this sand globe, somewhat larger than the sponge, could then be lifted, with the sponge inside, and put into a globe of water that would completely surround both while the water interpenetrated the whole mass, filling all the space between the grains of sand, that would give us a fair idea of the relationship of these three regions of nature. The sponge would represent that physical region, enveloped and interpenetrated by the sand representing the astral region. The mental region would be represented by the water which entirely surrounds and interpenetrates every particle of both the others. Holding this picture in mind a moment, it is easy to see how a force acting on the sand and moving the grains from point to point, need not in the least disturb the sponge; and how, also, force acting on the molecules of water need not affect anything but the water, although the molecules be moved freely through the entire mass. As a matter of fact, something like that is just what is occurring on these invisible planes of the universe. All the activities of life go forward on each without in the least interfering with any other.

What is it that makes these natural divisions, these regions of nature, these grades of matter growing finer and rarer, and that so completely separates them that they seem to not exist for each other? It is the inherent qualities peculiar to them, and which may be illustrated by the vibration of the matter of each region. It may be crudely represented by the difference that exists between ice, water and steam. We can take the visible solid called ice, and by the application of heat raise the rate of vibration until it becomes the visible liquid called water. We can continue the process until we change 4
