VII. Details From the Domain of Spiritual Science

The length of time between death and a new birth is determined by the fact that as a rule the I of man returns into the physical world only when this world has been so transformed as to give opportunity for new experiences. While the Ego is in the spiritual worlds, man's earthly dwelling-place is changing. In one respect this change is connected with the changes that are taking place in the great Universe—changes for example, in the relative position of the Earth to the Sun. Periodic changes involving cosmic repetitions are connected with the development of new conditions on the Earth. They find expression, for example, in the fact that the region of the heavens where the Sun rises at the vernal equinox makes an entire circuit in about 26,000 years. Throughout this period of the vernal point has therefore been moving from one region of the heavens to another, and in a twelfth of this period of time—that is to say, in about 2,100 years—conditions on the Earth will have altered sufficiently for the soul to be able to have essentially new experiences upon Earth. Moreover as these experiences differ according to whether one is incarnating as a woman or as a man, two incarnations will as a rule take place during this time—one as a man, one as a woman. However, these things also depend upon the forces gathered during earthly life—forces the individual takes with him through the gate of death. Therefore all such indications as have been given here are only valid in the most general sense; there will be many and manifold individual variations.
