This fine work is one of the most significant early works of the well-known Rudolf Steiner; one of the leaders of Theosophical thought before schisming from Annie Besants' faction and forming Anthroposophy. This text lists the steps of initiation in general and includes a fairly good autobiographical entry on Steiner himself, written by Edouard Schure. This inclusion is why I chose to edit from the second, rather than first, edition.
