“Madame Helena Petrovna Blavatsky was a clear favorite of Manly Hall’s, as he had a deep respect for her work and realized its importance to the esoteric and metaphysical community. Her “Isis Unveiled” and “Secret Doctrine” were both quoted extensively in Mr. Hall’s magnum opus, “The Secret Teachings of All Ages”.
In this lecture, given in Los Angeles on May 16, 1962, Hall sets the context for H.P. Blavatsky’s life and describes how difficult it was for a Western woman to travel in the East, parts of which were nearly inaccessible to even men at the time. She spent time in Asia, India, the Holy Land and the Americas (including studying the First Americans in the Southwestern United States).”
