In the ancient scriptures it is mentioned that human beings produced angels by their virtues; but this is only a symbological expression; it is not that human beings produced angels by their virtues, but that their virtues lifted their souls to the angels. One may ask, "If the souls who have settled in the angelic heaven are angels, then what makes them come to the earth?" The answer is that it is not the angels who have settled in the angelic heaven who come to the earth; for these rays have finished their creative power in manifesting as angels. If they had had a greater power they would certainly have gone farther, even to the physical plane, and would preferably have manifested as human beings; for the desire of every soul is to reach the culmination in manifestation, and that culmination is the stage of the human plane.
