group-soul as a whole, but is the individual astral body of the animal concerned, as will be later explained.

In each of these kingdoms it not only passes a period of time which is to our ideas almost incredibly long, but it also goes through a definite course of evolution, beginning from the lower manifestations of that kingdom and ending with the highest. In the vegetable kingdom, for example, the life-force might commence its career by occupying grasses or mosses and end it by ensouling magnificent forest trees. In the animal kingdom it might commence with mosquitoes or with animalculæ, and might end with the finest specimens of the mammalia.

The whole process is one of steady evolution from lower forms to higher, from the simpler to the more complex. But what is evolving is not primarily the form, but the life within it. The forms also evolve and grow better as time passes; but this is in order that they may be appropriate vehicles for more and more advanced waves of life. When the life has reached the highest level possible in the animal kingdom, it may then pass on into the human kingdom, under conditions which will presently be explained.

The outpouring leaves one kingdom and passes to another, so that if we had to deal with only one wave of this outpouring we could have in existence only one kingdom at a time. But the Deity sends out a constant succession of these waves, so that at any given time we find a number of them simultaneously in operation. We ourselves represent one such wave; but we find evolving alongside us another wave which ensouls the animal kingdom—a wave which came out from the Deity one stage later than we did. We find also the vegetable kingdom, which represents a third wave, and the mineral kingdom, which represents a fourth; and occultists know of the existence all round us of three elemental kingdoms, which represent the fifth, sixth and seventh waves. All these, however, are successive ripples of the same great outpouring from the Second Aspect of the Deity.

We have here, then, a scheme of evolution in which the divine Life involves itself more and more deeply in matter, in order that through that matter it may receive vibrations which could not otherwise affect it—impacts from without, which by degrees arouse within it rates of undulation corresponding to their own, so that it learns to respond to them. Later on it learns of itself to generate these rates of undulation, and so becomes a being possessed of spiritual powers.

We may presume that when this outpouring of life originally came forth from the Deity, at some level altogether beyond our power of cognition, it may perhaps have been homogeneous; but when it first comes within practical cognizance, when it is itself in the intuitional world, but is ensouling bodies made of the matter of the higher mental world, it is already not one huge world-soul but many souls. Let us suppose a homogeneous outpouring, which may be considered as one vast soul, at one end of the scale; at the other, when humanity is reached, we find that one vast soul broken up into millions of the comparatively little souls of individual men. At any stage between these two extremes we find an intermediate condition, the immense world-soul already subdivided, but not to the utmost limit of possible subdivision.

Each man is a soul, but not each animal or each plant. Man, as a soul, can manifest through only one body at a time in the physical world, whereas one animal soul manifests simultaneously through a number of animal bodies, one plant soul through a number of separate plants. A lion, for example, is not a permanently separate entity in the same way as a man is. When the man dies—that is, when he as a soul lays aside his physical body—he remains himself exactly as he was before, an entity separate from all other entities. When the lion dies, that which has been the separate soul of him is poured back into the mass from which it came—a mass which is at the same time providing the souls for many other lions. To such a mass we give the name of "group-soul".

To such a group-soul is attached a considerable number of lion bodies—let us say a hundred. Each of those bodies while it lives has its hundredth part of the group-soul attached to it, and for the time being this is apparently quite separate, so that the lion is as much an individual during his physical life as the man; but he is not a permanent individual. When he dies the soul of him flows back into the group-soul to which it belongs, and that identical lion-soul cannot be separated again from the group.

A useful analogy may help comprehension. Imagine the group-soul to be represented by the water in a bucket, and the hundred lion bodies by a hundred tumblers. As each tumbler is dipped into the bucket it takes out from it a tumblerful of water (the separate soul). That water for the time being takes the shape of the vehicle which it fills, and is temporarily separate from the water which remains in the bucket, and from the water in the other tumblers.

Now put into each of the hundred tumblers some kind of colouring matter or some kind of flavouring. That will represent the qualities developed by its experiences in the separate soul of the lion during its lifetime. Pour back the water from the tumbler into the bucket; that represents the death of the lion. The colouring matter or the flavouring will be distributed through the whole of the water in the bucket, but will be a much fainter colouring, a much less pronounced flavour when thus distributed than it was when confined in one tumbler. The qualities developed by the experience of one lion attached to that group-soul are therefore shared by the entire group-soul, but in a much lower degree.

We may take out another tumblerful of water from that bucket, but we can never again get exactly the same tumblerful after it has once been mingled with the rest. Every tumblerful taken from that bucket in the future will contain some traces of the colouring or flavouring put into each tumbler whose contents have been returned to the bucket. Just so the qualities developed by the experience of a single lion will become the common property of all lions who are in the future to be born from that group-soul, though in a lesser degree than that in which they existed in the individual lion who developed them.

That is the explanation of inherited instincts; that is why the duckling which has been hatched by a hen takes to the water instantly without needing to be shown how to swim; why the chicken just out of its shell will cower at the shadow of a hawk; why a bird which has been artificially hatched, and has never seen a nest, nevertheless knows how to make one, and makes it according to the traditions of its kind.

Lower down in the scale of animal life enormous numbers of bodies are attached to a single group-soul—countless millions, for example, in the case of some of the smaller insects; but as we rise in the animal kingdom the number of bodies attached to a single group-soul becomes smaller and smaller, and therefore the differences between individuals become greater.

Thus the group-souls gradually break up. Returning to the symbol of the bucket, as tumbler after tumbler of water is withdrawn from it, tinted with some sort of colouring matter and returned to it, the whole bucketful of water gradually becomes richer in colour. Suppose that by imperceptible degrees a kind of vertical film forms itself across the centre of the bucket, and gradually solidifies itself into a division, so that we have now a right half and a left half to the bucket, and each tumblerful of water which is taken out is returned always to the same section from which it came.

Then presently a difference will be set up, and the liquid in one half of the bucket will no longer be the same as that in the other. We have
