A Textbook of Theosophy

by C. W. Leadbeater

The matter of which all these interpenetrating worlds are built is essentially the same matter, but differently arranged and of different degrees of density. Therefore the rates at which these various types of matter normally vibrate differ also. They may be considered as a vast gamut of undulations consisting of many octaves. The physical matter uses a certain number of the lowest of these octaves, the astral matter another group of octaves just above that, the mental matter a still further group, and so on.

Not only has each of these worlds its own type of matter; it has also its own set of aggregations of that matter—its own substances. In each world we arrange these substances in seven classes according to the rate at which their molecules vibrate. Usually, but not invariably, the slower oscillation involves also a larger molecule—a molecule, that is, built up by a special arrangement of the smaller molecules of the next higher subdivision. The application of heat increases the size of the molecules and also quickens and amplifies their undulation, so that they cover more ground, and the object, as a whole expands, until the point is reached where the aggregation of molecules breaks up, and the latter passes from one condition to that next above it. In the matter of the physical world the seven subdivisions are represented by seven degrees of density of matter, to which, beginning from below upwards, we give the names solid, liquid, gaseous, etheric, superetheric, subatomic and atomic.

The atomic subdivision is one in which all forms are built by the compression into certain shapes of the physical atoms, without any previous collection of these atoms into blocks or molecules. Typifying the physical ultimate atom for the moment by a brick, any form in the atomic subdivision would be made by gathering together some of the bricks, and building them into a certain shape. In order to make matter for the next lower subdivision, a certain number of the bricks (atoms) would first be gathered together and cemented into small blocks of say four bricks each, five bricks each, six bricks or seven bricks; and then these blocks so made would be used as building stones. For the next subdivision several of the blocks of the second subdivision cemented together in certain shapes would form building-stones, and so on to the lowest.

To transfer any substance from the solid condition to the liquid (that is to say, to melt it) is to increase the vibration of its compound molecules until at last they are shaken apart into the simpler molecules of which they were built. This process can in all cases be repeated again and again until finally any and every physical substance can be reduced to the ultimate atoms of the physical world.

Each of these worlds has its inhabitants, whose senses are normally capable of responding to the undulations of their own world only. A man living (as we are all doing) in the physical world sees, hears, feels, by vibrations connected with the physical matter around him. He is equally surrounded by the astral and mental and other worlds which are interpenetrating his own denser world, but of them he is normally unconscious, because his senses cannot respond to the oscillations of their matter, just as our physical eyes cannot see by the vibrations of ultra-violet light, although scientific experiments show that they exist, and there are other consciousnesses with differently-formed organs who can see by them. A being living in the astral world might be occupying the very same space as a being living in the physical world, yet each would be entirely unconscious of the other and would in no way impede the free movement of the other. The same is true of all other worlds. We are at this moment surrounded by these worlds of finer matter, as close to us as the world we see, and their inhabitants are passing through us and about us, but we are entirely unconscious of them.

Since our evolution is centred at present upon this globe which we call the earth, it is in connection with it only that we shall be speaking of these higher worlds, so in future when I use the term "astral world" I shall mean by it the astral part of our own globe only, and not (as heretofore) the astral part of the whole solar system. This astral part of our own world is also a globe, but of astral matter. It occupies the same place as the globe which we see, but its matter (being so much lighter) extends out into space on all sides of us further than does the atmosphere of the earth—a great deal further. It stretches to a little less than the mean distance of the moon, so that though the two physical globes, the earth and the moon, are nearly 240,000 miles apart, the astral globes of these two bodies touch one another when the moon is in perigee, but not when she is in apogee. I shall apply the term "mental world" to the still larger globe of mental matter in the midst of which our physical earth exists. When we come to the still higher globes we have spheres large enough to touch the corresponding spheres of other planets in the system, though their matter also is just as much about us here on the surface of the solid earth as that of the others. All these globes of finer matter are a part of us, and are all revolving round the sun with their visible part. The student will do well to accustom himself to think of our earth as the whole of this mass of interpenetrating worlds—not only the comparatively small physical ball in the centre of it.

Chapter IV

THE EVOLUTION OF LIFE

All the impulses of life which I have described as building the interpenetrating worlds come forth from the Third Aspect of the Deity. Hence in the Christian scheme that Aspect is called "the Giver of Life", the Spirit who brooded over the face of the waters of space. In Theosophical literature these impulses are usually taken as a whole, and called the First Outpouring.

When the worlds had been prepared to this extent, and most of the chemical elements already existed, the Second Outpouring of life took place, and this came from the Second Aspect of the Deity. It brought with it the power of combination. In all the worlds it found existing what may be thought of as elements corresponding to those worlds. It proceeded to combine those elements into organisms which it then ensouled, and in this way it built up the seven kingdoms of Nature. Theosophy recognizes seven kingdoms, because it regards man as separate from the animal kingdom and it takes into account several stages of evolution which are unseen by the physical eye, and gives to them the mediæval name of "elemental kingdoms".
