A man of high moral principles also needs parents who transmit a physical body suitable for the functioning of his moral gifts. And he has these parents and no others because he is this particular kind of individuality.
The individuality himself seeks his parents, although under the guidance of higher Beings. From the point of view of mother-love many people take exception to this fact. They are fearful that they might lose something if the child were not to inherit certain qualities from the mother. True knowledge, however deepens mother-love, for it reveals that this love is present before birth, even before conception, as a force which guided the child to the mother. The child loves the mother even before birth and mother-love is the reciprocal force. Spiritually regarded, therefore, mother-love extends to the time before birth; it is rooted in mutual feelings of love.
