If you study Crowley or Thelema you will encounter some common themes. This introduction deals with some of the major themes, but only in summary form.
Real study requires independent work with the primary sources.
A traditional introduction to a religious system would set forth specific teachings and practices that its members would be expected to echo with one voice, but Thelema recognizes the validity and holiness of many different voices. This introduction takes the form of five different voices with five different agendas. Your voice is your own to evolve. Your views may or may not resemble any of the views of this introduction. They are composite voices drawn loosely from the real world.
