Alfred Percy Sinnett was one of the most significant members of the Theosophical Society. In "The Occult World," he gave long extracts from his early correspondence with Mahatma Koot Hoomi, describing the higher mysteries of nature possessed by the Indian "Mahatmas." In addition, he explained in detail many of the occult phenomena that Madame Blavatsky performed while she was in Simla. The readers will not leave this fantastic work without spiritual growth.
