Although this organ was later “removed” also by Great Nature from their common presences, yet owing to a cosmic law expressed by the words “the assimilation of the results of oft-repeated acts” – according to which law, from the frequent repetition of one and the same act there arises in every “world concentration” under certain conditions a predisposition to produce similar results – this law-conformable predisposition which arose in our forefathers was transmitted by heredity from generation to generation, so that when their descendants in the process of their ordinary existence established numerous conditions which proved to be congenial for the said law-conformableness, from that time on the consequences of the various proper ties of this organ arose in them, and being assimilated owing to transmission by heredity from generation to generation, they ultimately acquired almost the same manifestations as those of their ancestors.
