Scientology is a body of beliefs and related practices developed by American science fiction author L. Ron Hubbard. Hubbard began Scientology in 1952 as a self-help philosophy, an outgrowth of his earlier self-help system, Dianetics, and later described it as a new religion. He said that it offered an exact methodology to help humans achieve awareness of their spiritual existence across many lifetimes and, simultaneously, to become more effective in the physical world. The name "Scientology" is also used to refer to the often controversial Church of Scientology, the largest organization promoting the practice of Scientology, which is itself part of a network of affiliated organizations that claim ownership and sole authority to disseminate Dianetics and Scientology.
