This book, without any doubt teachs you about the OCCULTISM, to work and learn to command the spiritual forces to YOUR FAVOR, both demonic forces, as the forces of good. However this first book deals more specifically in AS SORT, and COMMAND the demonic spirits according to their functions because each spirit belongs to a ORDER, which is dominated by a BOSS. So you learn to call them and make it fulfill all your wishes of course, you follow the rituals as explained throughout the book. I warn that this book is very SERIOUS therefore everything to learn to use wisely, as well as the great Magi of the past did, including SOLOMON who was one of the largest, and got everything he wanted.
