In the first place, they were endowed with powers infinitely superior to those possessed by men to-day, even the most respected old men and the most celebrated magicians. They are attributed virtues which we may speak of as miraculous: "They could travel on, or above, or beneath the ground; by opening a vein in the arm, each of them could flood whole tracts of country or cause level plains to arise; in rocky ranges they could make pools of water spring into existence, or could make deep gorges and gaps through which to traverse the ranges, and where they planted their sacred poles (nurtunja), there rocks or trees arose to mark the spot."[788] It is they who gave the earth the form it has at present. They created all sorts of beings, both men and animals. They are nearly gods. So their souls also have a divine character. And since the souls of men are these ancestral souls reincarnated in the human body, these are sacred beings too. In the second place, these ancestors were not men in the proper sense of the word, but animals or vegetables, or perhaps mixed beings in which the animal or vegetable element predominated: "In the Alcheringa," say Spencer and Gillen, "lived ancestors who, in the native mind, are so intimately associated with the animals or plants the name of which they bear that an Alcheringa man of, say, the kangaroo totem may sometimes be spoken of either as a man-kangaroo or a kangaroo-man. The identity of the human individual is often sunk in that of the animal or plant from which he is supposed to have originated."[789] Their immortal souls necessarily have the same nature; in them, also, the human element is wedded to the animal element, with a certain tendency for the latter to predominate over the former. So they are made of the same substance as the totemic principle, for we know that the special characteristic of this is to present this double nature, and to synthesize and confound the two realms in itself.
