ucket, as tumbler after tumbler of water is withdrawn from it, tinted with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 then
practically two buckets, and when this stage is reached in a group-soul it
splits into two, as a cell separates by fission. In this way, as the
experience grows ever richer, the group-souls grow smaller but more
numerous, until at the highest point we arrive at man with his single
individual soul, which no longer returns into a group, but remains always
separate.

One of the life-waves is vivifying the whole of a kingdom; but not every
group-soul in that life-wave will pass through the whole of that kingdom
from the bottom to the top. If in the vegetable kingdom a certain
group-soul has ensouled forest trees, when it passes on into the animal
kingdom it will omit all the lower stages--that is, it will never inhabit
insects or reptiles, but will begin at once at the level of the lower
mammalia. The insects and reptiles will be vivified by group-souls which
have for some reason left the vegetable kingdom at a much lower level than
the forest tree. In the same way the group-soul which has reached the
highest levels of the animal kingdom will not individualize into primitive
savages, but into men of somewhat higher type, the primitive savages being
recruited from group-souls which have left the animal kingdom at a lower
level.

Group-souls at any level or at all levels arrange themselves into seven
great types, according to the Minister of the Deity through whom their life
has poured forth. These types are clearly distinguishable in all the
kingdoms, and the successive forms taken by any one of them form a
connected series, so that animals, vegetables, minerals and the varieties
of the elemental creatures may all be arranged into seven great groups, and
the life coming along one of those lines will not diverge into any of the
others.
