We cannot delay on details; I can only trace hastily the outline, showing you how real is the truth that underlies the story, and as that gradually goes on and the types are ready, there comes the whelming of the world under the waters, and the great continents vanish for a time. Then comes the third Avatâra, the Vârâha. No earth is to be seen; the waters of the flood have overwhelmed it. The types that are to be produced on earth are waiting in the higher region for place on which to manifest. How shall the earth be brought up from the waters which have overwhelmed it? Now once again the great Helper is needed, the God, the Protector of Evolution. Then in the form of a mighty Boar, whose form filled the heaven, plunging down into the waters that He alone could separate, the Great One descends. He brings up the earth from the lower region where it was lying awaiting His coming; and the land rises up again from below the surface of the flood, and the vast Lemurian continent is the earth of that far-off age. Here science has a word to say, rightly enough, that on the Lemurian continent were developed many types of life, and there the mammals first made their appearance. Quite so; that was exactly what the sages taught thousands upon thousands of years ago; that when the Boar, the great type of the mammal, plunged into the waters to bring up the earth, then was started the mammalian evolution, and the continent thus rescued from the waters was crowded with the forms of the mammalian kingdom. Just as the Fish had typified the Silurian epoch, just as the Tortoise had started on its way the great amphibian evolution, so did the Boar, that typical mammal, start the mammalian evolution, and we come to the Lemurian continent with its wonderful variety of forms of mammalian life. Not so very ignorant after all, you see, the ancient writings! For men are only re-discovering to-day what has been in the hands of the followers of the Ṛishis for thousands, tens of thousands of years.
