With this audience Rudolf Steiner was able to take this knowledge for granted and it is therefore only touched upon or partially dealt with in the different lectures of the Course.
Seven Stages of Consciousness (Planetary Evolutions)
Each of these develops through Seven Conditions of Life (Rounds, Kingdoms)
Each of these pass through Seven Conditions of Form (Globes)
Every Condition of Form again goes through 7 x 7 stages of development; for instance our present Fourth Condition of Form (of the Mineral Kingdom, within the Fourth Planet, the Earth) goes through the so-called 7 Root-Races (ages or Main Periods of Time) and again through the Cultural Epochs of our present Fifth Root-Race (Post-Atlantean Age).
After every Kingdom there is a short Pralaya (Sleep Condition) and after each Condition of Consciousness a long Pralaya.

According to Notes of a Lecture-Cycle held in Berlin, October/November 1904 thus one year before the present course Rudolf Steiner made the diagram (next) and the appended explanation:
Thus man goes through the following Evolution:
The 25th stage is always the deepest, densest, middle stage. We are now on the fourth Planet, on the 25th. stage, thus on the densest stage of all. On the seventh Planet, in the seventh kingdom, the human kingdom, and the seventh Form, the archetypal, the highest perfection of human evolution will be attained. Man will then have his archetypal form; he will be a god-like human being and possess an all-embracing spiritual consciousness.
(Berlin, 29th October 1904)
