Lecture III
The third member of man's being is the spirit. The physical or corporeal is expressed in the line of descent from father to son. The son becomes a father and this son in his turn becomes a father and so on through the generations. In this way inherited characteristics are transmitted from one generation to another. The psychic life as such is created with the birth of the individual and persists after death. Its destiny is determined by the extent to which the soul can remain in touch with the Kingdom of Heaven. The spirit persists through repeated incarnations on Earth and everything depends upon the kind of bodies it can find in the course of its successive lives on Earth. On the one hand there is the line of descent on the physical plane, in which the spirit participates; but the line of descent is permeated with physically inherited characteristics. What potentialities the spirit finds in the course of its successive incarnations depends upon whether mankind has progressed or deteriorated. Out of the spirit one cannot create bodies to order; one can only select those which are relatively best suited to the spirit that is about to incarnate; one cannot tailor them to measure.
