The landmark book presents L. Ron Hubbard’s discovery of the reactive mind that underlies and enslaves Man. It’s the source of nightmares, unreasonable fears, upsets and insecurity. And here is the way to get rid of it and achieve the long sought goal of Clear. This is the complete handbook of Dianetics procedure and, with it, any two reasonably intelligent people can break the chains that have held them prisoner to the upsets and trauma of the past. A bestseller for more than half a century and with tens of millions of copies in print, translated in more than fifty languages and used in more than 100 countries of Earth, Dianetics is indisputably the most widely read and influential book about the human mind ever written.
