But this conclusion presupposes that the tribes of which we have just been speaking admit the doctrine of reincarnation. Now according to Strehlow, this doctrine is unknown to the Arunta, the society which Spencer and Gillen have studied the longest and the best. If, in this particular case, these two observers have misunderstood things to such an extent, their whole testimony would become suspect. So it is important to determine the actual extent of this divergence.

According to Strehlow, after the soul has once been definitely freed from the body by the rites of mourning, it never reincarnates itself again. It goes off to the isles of the dead, where it passes its days in sleeping and its nights in dancing, until it returns again to earth. Then it comes back into the midst of the living and plays the rôle of protecting genius to the young sons, or if such are lacking, to the grandsons whom the dead man left behind him; it enters their body and aids their growth. It remains thus in the midst of its former family for a year or two, after which it goes back to the land of the souls. But after a certain length of time it goes away once more to make another sojourn upon earth, which is to be the last. A time will come when it must take up again, and with no hope of return this time, the route to the isles of the dead; then, after various incidents, the details of which it is useless to relate, a storm will overtake it, in the course of which it will be struck by a flash of lightning. Thus its career is definitely terminated.[792]

So it cannot reincarnate itself; nor can conceptions and births be due to the reincarnation of souls which periodically commence new existences in new bodies. It is true that Strehlow, as Spencer and Gillen, declares that for the Arunta commerce of the sexes is in no way the determining condition of generation,[793] which is considered the result of mystic operations, but different from the ones which the other observers told us about. It takes place in one or the other of the two following ways:

Wherever an ancestor of the Alcheringa[794] times is believed to have entered into the ground, there is either a stone or a tree representing his body. The tree or rock which has this mystic relation with the departed hero is called nanja according to Spencer and Gillen,[795] or ngarra according to Strehlow.[796] Sometimes it is a water-hole which is believed to have been formed in this way. Now, on each of these trees or rocks and in each of these water-holes, there live embryo children, called ratapa,[797] which belong to exactly the same totem as the corresponding ancestor. For example, on a gum-tree representing an ancestor of the kangaroo totem there are ratapa, all of which have the kangaroo as their totem. If a woman happens to pass it, and she is of the matrimonial class to which the mothers of these ratapa should belong,[798] one of them may enter her through the hip. The woman learns of this act by the characteristic pains which are the first symptoms of pregnancy. The child thus conceived will of course belong to the same totem as the ancestor upon whose mystical body he resided before becoming incarnate.[799]

In other cases, the process employed is slightly different: the ancestor himself acts in person. At a given moment he leaves his subterranean retreat and throws on to the passing woman a little churinga of a special form, called namatuna.[800] The churinga enters the body of the woman and takes a human form there, while the ancestor disappears again into the earth.[801]

These two ways of conception are believed to be equally frequent. The features of the child will reveal the manner in which he was conceived; according to whether his face is broad or long, they say that he is the incarnation of a ratapa or a namatuna. Beside these two means of fecundation, Strehlow places a third, which, however, is much more rare. After his namatuna has penetrated into the body of the woman, the ancestor himself enters her and voluntarily submits to a new birth. So in this case, the conception is due to a real reincarnation of the ancestor. But this is very exceptional, and when a man who has been conceived thus dies, the ancestral soul which animated him goes away, just like ordinary souls, to the isles of the dead where, after the usual delays, it is definitely annihilated. So it cannot undergo any further reincarnations.[802]

Such is the version of Strehlow.[803] In the opinion of this author it is radically opposed to that of Spencer and Gillen. But in reality it differs only in the letter of the formulæ and symbols, while in both cases we find the same mythical theme in slightly different forms.

In the first place, all the observers agree that every conception is the result of an incarnation. Only according to Strehlow, that which is incarnated is not a soul but a ratapa or a namatuna. But what is a ratapa? Strehlow says that it is a complete embryo, made up of a soul and a body. But the soul is always represented in material forms; it sleeps, dances, hunts, eats, etc. So it, too, has a corporal element. Inversely, the ratapa is invisible to ordinary men; no one sees it as it enters the body of the woman;[804] this is equivalent to saying that it is made of a matter quite similar to that of the soul. So it hardly seems possible to differentiate the two clearly in this regard. In reality, these are mythical beings which are obviously conceived after the same model. Schulze calls them the souls of children.[805] Moreover, the ratapa, just like the soul, sustains the closest relations with the ancestor of which the sacred tree or rock is the materialized form. It is of the same totem as this ancestor, of the same phratry and of the same matrimonial class.[806] Its place in the social organization of the tribe is the very one that its ancestor is believed to have held before it. It bears the same name,[807] which is a proof that these two personalities are at least very closely related to one another.

But there is more than this; this relationship even goes as far as a complete identification. In fact, it is on the mystic body of the ancestor that the ratapa is formed; it comes from this; it is like a detached portion of it. So it really is a part of the ancestor which penetrates into the womb of the mother and which becomes the child. Thus we get back to the conception of Spencer and Gillen: birth is due to the reincarnation of an ancestral personage. Of course it is not the entire person that is reincarnated, it is only an emanation from him. But this difference has only a secondary interest, for when a sacred being divides and duplicates itself, all of its essential characteristics are to be found again in each of the fragments into which it is broken up. So really the Alcheringa ancestor is entire in each part of himself which becomes a ratapa.[808]

The second mode of conception distinguished by Strehlow has the same significance. In fact, the churinga, and more especially the particular churinga that is called the namatuna, is considered a transformation of the ancestor; according to Strehlow,[809] it is his body, just as the nanja tree is. In other words, the personality of the ancestor, his churinga and his nanja tree, are sacred things, inspiring the same sentiments and to which the same religious value is attributed. So they transmute themselves into one another: in the spot where an ancestor lost his churinga, a sacred tree or rock has come out of the soil, just the same as in those places where he entered the ground himself.[810] So there is a mythological equivalence of a person of the Alcheringa and his churinga; consequently, when the former throws a namatuna into the body of a woman, it is as if he entered into it himself. In fact, we have seen that sometimes he does enter in person after the namatuna; according to other stories he precedes it; it might be said that he opens up the way for it.[811] The fact that these two themes exist side by side in the same myth completes the proof that one is only a doublet of the other.
