Opportunity and correctness of producing the forms which incarnating souls will assume. The idea of the need for rapid procreation and the production of large families through which the state can achieve its end will be changed. The preparation of adults for the duties of parenthood and their training in the basic necessities of the coming child will shift increasingly to the mental and spiritual levels of consciousness and be less given to physical preparations. 
The light which is in the parents, which in the days to come will be seen clairvoyantly by an increasing number of people, will be scientifically related to the embryonic light in the child, and the thread of light connecting parent and child (of which the umbilical cord is the exoteric symbol) will be skillfully and patiently constructed. The child will come into incarnation with its light body already embedded and functioning in the physical body and this will be due to the intelligent mental work of the parents. This is not so today, except in the case of very advanced egos, for the light body is inchoate and diffused and simply hovers over the physical form of the child, waiting for an opportunity to enter and irradiate the consciousness. Thus will be brought about an integration in the light substance of the planet which is lacking at this time; and the production of this integration will be definitely initiated by the trained parents of the new age and facilitated, as the child matures, by the teaching and influence of the illumined educator."
