The race of man is far more than the physical race however. You see him in but one stage of development. When an individual leaves your system it is for other systems. He has learned his A B C’s, but that is all. There are some exceptions—identities that choose, then, to return and teach. They are not in the same league, so to speak, as those whose reincarnational cycles are not complete.

They may return, even enduring violence, as a man might set up a school amid a jungle of savages. And yet even with this there are advances made within the system itself. A nuclear weapon in the hands of the inhabitants of middle-age Europe would have been used almost immediately, and with nary a qualm, to wipe out all but Christendom.

They exploded, and were recreated many times, disappeared and returned. They would seem to pulsate. To you they would seem to disappear for eons. To them their existence was continuous. As atoms and molecules give your chairs a reality within your system even though the atoms and molecules come and go, so this planetary system still retains its reality. (Pause.)

There can be in your terms some loss of memory, complications that confuse the knowledge of origin. When the situation does occur, there is always a division of forces, some entities returning to form, and others not entering the process. These watch, keeping their memories and knowledge intact, and acting as directors, against whose memories the new models are formed.
