"The members of the Brotherhood are eternally alert and watchful, and are continuously acting as a Guardian Wall (to adopt the phrase of H. P. Blavatsky), around mankind, shielding it against dangers both of a cosmic and terrestrial character. Mankind little knows what it owes to the great sages and seers. (Chapter 22)"
