Golden Truths is a book purportedly authored by Myles de Selby which describes the God-Machine.
Stephen Escher discovers a copy of the book in 2012. He describes it as a mass-market paperback from the 1970s, and notes that the copyright page—while missing certain key information—mentions a first publication in 1937. Considering what happened to de Selby in 1916, it is unclear whether the book was actually authored by him, or if someone else published it under his name.
The book begins much like any other New Age self-help book, describing how you too can manipulate the machinery of the world to provide yourself with fame, fortune and sexual potency. However, partway through the text begins to describe Infrastructure in explicit detail, including maps to specific access points and instructions on how to enter the God-Machine's facilities.
