The following text is transcribed from oral instructions given by Samael Aun Weor to a student. The transcribed text was initially published by that student decades ago in Spanish in the form of a narrative, and included many personal anecdotes and writings unrelated to the teachings. In later years, other Gnostic students decided to publish an edition that removed the extraneous material, resulting in a series of completely unrelated chapters. In 2008, Glorian Publishing translated and published the first English edition of that book. However, new readers were very confused by the jumbled collection of chapters, causing many to believe that Samael Aun Weor wrote the book in that form, which reflected badly on the teachings. Therefore, in this new edition, we have removed the extraneous chapters and focused entirely on the exercises. For those who are interested in reading the other chapters, they are available as online articles.
