"It is wrong to think that the mixing of classes can affect the karma of people in a negative way. At the present time, quite often, the healthy, spiritually sound peasant family offers the best environment for a highly developed spirit. One's having been born in a palace or in a corner of a cobbler's shack should not be deemed the result of a mixing of classes, but, rather, to have been for the purpose of fulfilling a personal karma or else a certain mission. Thus, Boehme was a cobbler, but this was for the very reason that in those days this was the way in which he could best fulfil his great mission, in comparative peace. The dreadful karma of humanity is the result of the violation of cosmic laws, beginning with birth, but it is not the result of the mixing of social classes. Thus, marriage will be scientifically treated in the future. It is even said that people should conjoin according to their affinity with certain elements. 5 May 1934"
