"The Theosophical conception, as widely put forward among thoughtful people, asks them to consider the coming of World Teachers as normal, not as abnormal; as under a certain definite law, and not as a breach of continuity; as part of the Divine plan working out in human evolution, by which these Teachers form a long succession, appearing at quite definite intervals, and accompanied by certain definite signs or conditions in the civilization of the world to which they come."
