Charles Leadbeater was born in England in 1847 (1854 according to some sources). After dropping out of Oxford due to hard times, Leadbeater became an ordained priest, but then became quite active in the occult. This led to his becoming a member of the Theosophical Society in 1883. Leadbeater became one of its most famous participants.
The combination of a bright mind, scientific knowledge, and interest in the paranormal led him to publish many books on many diverse topics. One of them, Dreams: What They Are and How They Are Caused (1898), was one of the first works to touch upon the phenomenon of lucid dreaming. Leadbeater’s writing is saddled with a ton of esoteric terms and theories. In it, the term astral plane is predominantly used for lucid dreaming. Nevertheless, the book is not without some helpful guidelines concerning techniques.
Charles Leadbeater passed away in 1934.
