You have in that first stage what the geologists call the Silurian Age, the age of fishes, when the great divine manifestation was of all these forms of life. The Purâṇa rightly starts in the previous Kalpa, rightly starts the manifestations with the manifestation in the form of the fish. Not so very ridiculous after all, you see, when read by knowledge instead of by ignorance; a truth, as the Purâṇas are full of truth, if they were only read with intelligence and not with prejudice. But some of you may say that there is confusion about these first Avatâras; in several accounts we find that the Boar stands the first; that is true, but the key of it is this; the Boar Avatâra initiated that evolution which was followed unbrokenly by the human; whereas the other two bring in great stages, each of which is regarded as a separate kalpa; and if you look into the _Viṣhṇu Purâṇa_ you will find there the key; for when that begins to relate the incarnation of the Boar, there is just a sentence thrown in, that the Matsya and Kûrma Avatâras belong to previous kalpas. Now if we take the theosophical nomenclature, we find each of these kalpas covers what we call a Root Race, and you may remember that the first Root Race of humanity had not human form at all but was simply a floating mass able to live in the waters which then covered the earth, and only showing the ordinary protoplasmic motions connected with such a type of life and possible at that stage of its evolution. It was a seed of form rather than a form itself; it was the seed planted by the Manu in the waters of the earth, that out of that humanity might evolve. But the general course of physical evolution passed through the stage of the fish; and geology there gives a true fact, though it does not understand, naturally, the hidden meaning; while the Purâṇa gives you the reality of the manifestation, and the deeper truth that underlies the stages of the evolving world.
