There is no higher development without other [development] being thrust down into the depths. The mineral, plant and animal kingdoms were thrust down in this way. Whoever develops himself upwards, takes upon himself a tremendous responsibility, that is the great tragedy; the corollary of every saint is that a great number of beings are thrust down.
There would be no development if this kind of thrusting down did not take place. A man must continually thrust others down, as he develops himself upwards. That is why all development which takes place out of self-interest is evil and reprehensible; it is only justifiable if done for the development of other beings. Only he who would raise up those who have been thrust down is fit for development.
