"Astral Plane: Its Scenery, Inhabitants, and Phenomena" is a seminal work on the subject of the nether-world. Written in 1895 by C. W. Leadbeater, an Anglican Priest who joined the Theosophical Society in 1883, "Astral Plane" is an interesting examination of ideas on the after-life as proposed by new age philosophies such as Theosophy.
