Scientology 8-8008 (December 1952): Continuing his exploration of the thetan and associated characteristics, this book summarizes the description of the behavior and potentials of the thetan as detailed in the Philadelphia Doctorate Course lectures of the same period. The title of the book is a symbolic explanation of the route of processing outlined in the book, which basically means that the attainment of infinity is accomplished by reducing the apparent infinity of the physical universe to zero and by increasing the apparent zero of the individual's own universe to infinity. The state of Operating Thetan is first discussed here.
