Lecture I
Our experience of earthly life is, after all, fragmentary. Looking back over earthly life with ordinary consciousness, it appears to us as a single, continuous stream. But what has it been in reality? A day that has already become shadowy was followed by a night of which ordinary consciousness has no remembrance. Another day is followed by another night—and so it goes on. In memory we string together only the days but in a true retrospect the days must always be interrupted by what we have experienced during the nights. Ordinary consciousness fails here, and with a certain justification, because it is extinguished in sleep. When we are among these Moon Beings who were once the primeval Teachers of humanity, we live through precisely what we experienced during the nights here on the Earth. The length of time this form of existence in the Moon sphere lasts can therefore be computed. If a man is not an abnormally long sleeper he spends about one third of the duration of his earthly life in sleep. And life in the Moon sphere lasts for just so long, that is to say, for about one third of the duration of the life on Earth. A man who reaches the age of twenty spends about seven years in the Moon sphere; one who reaches the age of sixty, about twenty years, and so on. We live among these Beings and they permeate us with their form of existence.
