Lecture I

Let’s begin with the planet nearest the Earth, the planet with whose history is bound up with the Earth's history, though only in a certain sense, and which once played an entirely different part in earthly life from the part it plays today. You know from my book Outline of Occult Science that there was once a cosmic age, relatively speaking not in a very remote past, when the Moon was still united with the Earth. The Moon then separated from the Earth and now circles around it.
