People often ask whether it wouldn’t be better to use the time that one uses for development for doing good deeds in the world. But occultists must reply that time that’s spent on development isn’t wasted. For a man can only work well and rightly for mankind by making himself more perfect. Outer deeds that seem to be ever so good can be harmful; one just doesn’t know it.
