This is Dr Israel Regardie s extended commentary on his years with the Great Beast and the life and works of his infamous former employer. Moreover, the book is an attempt at an insightful, if not com-pletely objective, analysis of the psychological processes that caused Crowley to tick so peculiarly. At the same time Regardie s observations might also give us some insight as to what might have been making Regardie tick so peculiarly. He recognised that the brilliance of Crowley s genius transcended and eclipsed his myriad (and serious) human flaws; he recognized it was his duty to mankind his duty to the advancement of human thought to allow the world to see the blazing sun of Crowley s genius and the soul-liberating message he tried to deliver. This book also represents the opening of Regardie s own eye to the spiritual significance of Crowley s contribution to the evolution of human conscious-ness, and to the importance of his own vital role and responsibility in presenting it to the world.
