"It is impossible to know anything in the occult sense of the present and future of human or planetary evolution without understanding that evolution in the past. For, that which presents itself to the occult student's observation when he watches the hidden events of the past, contains at the same time everything that he can learn of the present and future. In this book we have spoken of the Saturn, Sun, Moon and Earth evolutions. We cannot follow the evolution of the earth, as the occultist understands it, unless we observe the events of preceding evolutionary periods. For what meets us today, within the bounds of our earthly globe, comprises in a certain sense the facts of the evolution of the Moon, Sun and Saturn. The beings and things that took part in the evolution of the Moon have gone on developing, and all that now belongs to the earth, is the outcome of that development. (Chapter VI. The Present and Future Evolution of the World and of Humanity)"
