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.
