How shall we define occultism? The word is derived from the Latin occultus, hidden; so that it is the study of the hidden laws of nature. Since all the great laws of nature are in fact working in the invisible world far more than in the visible, occultism involves the acceptance of a much wider view of nature than that which is ordinarily taken. The occultist, then, is a man who studies all the laws of nature that he can reach or of which he can hear, and as a result of his study he identifies himself with these laws and devotes his life to the service of evolution.
