What can protect us from any aberrations which become superstition can be solely the pursuit of real knowledge, of seeing through the matters. Someone is always addicted to superstition who does not want to penetrate really into the depth of the matters. It anyway is in such a way that this longing for a certain quantity of superstition prevails absolutely.
With it, I pronounce the basic principle of superstition: as long as the human being remains only in the observation of the physical environment, as long as he does not want to penetrate to spiritual science, to the real knowledge of the spiritual primal grounds of the things, a certain need of superstition lives in him.
