We Are Climbing Jacob's Ladder
Rudolf Steiner: "What someone has engraved in their own etheric body and then carried through the gates of death out into the universal world-ether is destined, however, to undergo gradual changes. These changes are accomplished in the course of successive Earth incarnations, as the person experiences the whole of Earth existence. Just consider how much is contained in what a person thinks! Would it not be the most horrible thing imaginable if all men's thoughts were objectively engraved in the substance of the world and had to remain there eternally? But that is what would happen if, in the course of repeated lives on Earth, humanity were not in the position to be able to make good the thoughts that should not remain — to either improve them or eradicate them and replace them with something entirely different, and so on. That is one of the things established by an evolution through successive lives on Earth. It gives mankind the opportunity to improve on what it carries with it through the gates of death into the substance of the world, so that a person can strive for a final Earth incarnation which only leaves behind in the ether-substance of the world that which really can remain."
