Science of Survival was the follow-up to Hubbard's best-selling Dianetics: The Modern Science of Mental Health. It expanded significantly on Dianetics, setting out what Hubbard called the \"dynamics of behaviour\" and provided descriptions of new techniques of Dianetics processing that Hubbard described as being faster and simpler than those that he had advanced previously. In the book, Hubbard introduced two concepts that were later to become key elements of Scientology: theta and the tone scale. He also endorsed the concept of past lives, an issue that had been controversial in Dianetics but which Hubbard had come to embrace."@en .
