III. The Elemental World and the Heaven World. Waking Life, Sleep and Death.
After the lapse of the time during which the etheric body together with the astral body is emerging from the physical body after death, there comes the moment when the astral body, with the higher members, leaves the etheric body. The latter separates off and the memory-tableau fades away; but something of it remains; it is not wholly lost. What may be called ether- or life-substance dissipates in the cosmic ether, but a kind of essence remains and this can never be lost to the human being through his further journeyings. He bears this with him into all his future incarnations as a kind of extract from the life-tableau, even though he has no remembrance of it. Out of this extract is formed what is called, with concrete reality, the “Causal Body.” After every incarnation a new page is added to the Book of Life. This augments the life-essence and, if the past lives were fruitful, causes the next life to develop in the proper way. This is what causes a life to be rich or poor in talents, qualities and the like.
