Lecture III
Certain things that have been said in giving a brief glimpse into the occult course of human evolution will have indicated to you that the succession of incarnations as determined by the individual character and development of human beings, is modified through the intervention of spiritual forces from the higher Hierarchies. Reincarnation is by no means such a simple process in the evolution of humanity as a certain easy-going way of thinking likes to assume. It is, of course, a fact that man incarnates again and again, that the innermost core of his being appears over and over again in new incarnations; it is also true that there is a causal connection between earlier and later lives. Moreover there is the law of karma which gives expression to this causal connection. But over and above all this there is something else which is essential for understanding the historical course of the evolution of mankind. The course of human evolution would have been quite different if nothing except the causal connections between one incarnation and the next, or between the earlier and the later incarnations of the human being came into consideration. Other forces of great significance intervene perpetually in human life, in every incarnation, to a greater or less extent, and use the human being as an instrument. This applies particularly in the case of leading personalities in history. Hence it follows that purely individual karma is modified through the successive incarnations, and this is what actually happens.
