According to tradition, each Master or Mistress who was responsible for a particular Satanic Temple or group, was given on his or her assumption of that responsibility, a copy of the Black Book of Satan. The Black Book contained the basic Satanic rituals, instructions relating to ceremonial magick in general. In traditional Satanism (i.e. those using the Septenary System: this system also being known as the Hebdomadry) this practice continued until quite recently when the Grand Master representing traditional groups decided to allow Initiates of good standing to copy the work. The whole text of the traditional Black Book is included in the present work, together with several additional chapters (e.g. Self-Initiation; Organizing and Running a Temple). These additions make this present work a concise practical handbook for those seriously interested in the Black Arts.
