Scientology does not have sacred texts, like the Bible or the Quran. The principles, practice, and methods of Scientology are studied through the books, writings, and lectures of their founder, L. Ron Hubbard.
Published in the early years of Scientology, the Basic Books of Scientology were written in their entirety by L. Ron Hubbard.
The Basic Books include Dianetics: The Original Thesis, which was written in 1948 and circulated to a few friends. Copied and passed from one person to another, it later became widespread, prompting Hubbard to write Dianetics: The Modern Science of Mental Health in 1950, which is known as "Book One" by Scientologists. Dianetics: The Evolution of a Science reprints an Astounding Science Fiction article that introduced Dianetics prior to the publication of Book One.
In 1951, Hubbard published Science of Survival, which introduces some of the concepts that would later become core elements of Scientology. These included theta, the tone scale, the possibility of past lives, and a description of how theta interacts with the physical universe of matter, energy, space, and time (MEST).
Others include Self Analysis, Advanced Procedure and Axioms, and Handbook for Preclears, all published in 1951.
In 1952, Hubbard published A History of Man, in which Hubbard gives instructions on auditing, as well as the origins of the thetans on another planet, and the whole track of incidents known as space opera.
In 1952, Hubbard published Scientology 8-80, in which the laws by which a thetan can create energy and influence the environment around him are given, as well as Scientology 8-8008, which is sometimes described as one of the most important books in Scientology, as it deals with the way in which people perceive and thereby create the physical universe, as well as his own universe.
The Creation of Human Ability, published in 1954, puts together many of the processes introduced in Hubbard's earlier books and was intended as a reference book for auditors. It is one of the few writings in which Hubbard quotes the Bible.
That same year, he published Dianetics 55!, discussing an individual's communications with his environment. In 1956, Hubbard published Scientology: The Fundamentals of Thought, which includes all of the basic principles and processes of Dianetics and Scientology, the chief concept being that life is a game and the importance of knowing which game you're playing.
Other books that are not part of the Basic Books of Scientology are also either written by L. Ron Hubbard or compiled from other of his works. These include Excalibur (1938), How to Live Though an Executive (1953), Problems at Work (1956), and All Aout Radiation (1957), written by L. Ron Hubbard, Gene Denk, and Farley R. Spink. Others include Have You Lived Before This Life (1958), and one by Hubbard's wife, Mary Sue Hubbard, entitled The Book of E-Meter Drills (1965). Lastly in this category, by L. Ron Hubbard, are Introduction to Scientology Ethics (1968), Scientology: A New Slant on Life (1976), and The Way to Happiness (1981).Books published by the Church of Scientology after Hubbard's death include Clear Body, Clear Mind (1990), Art (1991), and The Scientology Handbook (1994).
Also significant is the Phoenix Lectures: Freeing the Human Spirit, a collection of lectures by L. Ron Hubbard.
Other publications that would be appropriate for this category are magazine publications by the Church of Scientology or any of the other Scientology organizations, or sites representing Scientology publishing companies.
