Published in 1889, The Key to Theosophy is, as its subtitle declares, a “Clear Exposition, in the Form of Question and Answer, of the Ethics, Science, and Philosophy for the Study of which The Theosophical Society has been Founded” In it, Blavatsky traces Wisdom-Religion, spiritualistic teachings, the true nature of the Spiritualistic phenomena, as well as the other fundamentals of Theosophy. The book includes a comprehensive glossary of theosophical terminology.
