Examines how and why esoteric schools have restricted admission to their secret societies and orders, and shrouded their practices in mystery. The knowledge guarded by these schools passed down through the ages, and revised from time to time by great teachers is a secret science that studies the causes that lie behind observable phenomena. Includes a new introduction by Gareth Knight. Index.
