4. Laws of Nature, Evolution of Consciousness and Repeated Earth Lives

You need only study sleep consciousness in order to see that the human being does not work together with his ego in sleep. Ego-consciousness presupposes imprisonment in a body, employment of the instruments of the senses and of the brain. Now, if during a single incarnation man is able only to a slight extent to make use of all that is given him in this incarnation, it should not seem surprising when clairvoyant consciousness tells us that a thorough search in the human ego, in so far as the latter manifests itself in its true form, discloses as its prime impulse, its predominant force, the longing for ever new earth lives, in order to fill and enrich this ego-consciousness more and more, to develop it to an ever higher state.
