THE BASICS are the foundation upon which the entirety of Dianetics and Scientology rests, containing the fundamentals, underlying principles and axioms that form the basis of all subsequent developments. Your training, both auditor and Solo, begins with a study of the Basics Books. Any Basics Books you have already studied in the org or on an extension course are credited toward your training checksheets. The chronological study of both Basics Books and Lectures provides a complete grounding in the subject and an effortless comprehension of all further studies in Scientology.
