One should not ask a question such as: Why do the spiritual powers not intervene in the affairs on the physical plane and bring order about? That ought not to be asked because what human beings do is often in direct revolt against the spiritual powers. Very often those in revolt are the very people who are forever talking about spirit, spirit, spirit. I recently read on the cover of a magazine an advertisement of some kind in which the word spirit was repeated ad nauseam. These days spirit dominates everything, it is enough to make one despair! Spirit is supposed to manufacture the germs and gas masks and what not. Everything is called spirit. The question is: do people realize what spirit this is?
