Real Genetic-engineering for peace & prosperity

The samskaras of the school of sanatana-dharma (man's eternal engagement) are highly suitable for creating an atmosphere for taking advantage of good stellar influences, and therefore garbhadhana-samskara, or the first seedling purificatory process prescribed for the higher castes, is the beginning of all pious acts to receive a good pious and intelligent class of men in human society. There will be peace and prosperity in the world due to good and sane population only; there is hell and disturbance only because of the unwanted, insane populace addicted to sex indulgence.
