9. Evolution of the Earth

Now just as man passes through the various stages of his life, as child, young man or woman, old man or woman, so so does a planet. Before Saturn manifested the flaky structures deposited within it, it was an Arupa-Devachan structure, then a Rupa-Devachan structure, and finally an astral structure. Then the flakes gradually disappear, and Saturn returns through the same stages into the darkness of Pralaya. A metamorphosis such as this, from the spiritual into the physical and then back again into the spiritual, is called in Theosophy a Round, or a Life-condition. Each Round can be divided into seven phases: Arupa, Rupa, Astral, Physical and back to Arupa.[^1] These phases, called “Globes”, are Form-conditions. But we must not imagine seven successive Globes; it is always the same planet which transforms itself, and its beings are transformed with it. Saturn passed through seven such Rounds or Life-conditions. In each Round its structure was being perfected, so that only in the seventh Round was its finally perfected form attained. Each Round has its seven transformations, or Form-conditions, so that Saturn will have passed through seven times seven, or forty-nine, metamorphoses. That is true of Saturn, and then of Sun, Moon and Earth; and in the future there will be three more planets: Jupiter, Venus and Vulcan.
