Magick Without Tears
Aleister Crowley
 The book consists of 80 letters to various students of magick. Originally to be titled Aleister Explains Everything, the letters offer his insights into both magick and Thelema—-Crowley's religious and ethical system—-with a clarity and wit often absent in his earlier writings. The individual topics are widely varied, addressing the orders O.T.O. and A∴A∴, Qabalah, Thelemic morality, Yoga, astrology, various magical techniques, religion, death, spiritual visions, the Holy Guardian Angel, and other issues such as marriage, property, certainty, and meanness. The book is considered by many as evidence that Crowley remained lucid and mentally capable at the end of his life, despite his addiction to heroin (prescribed for his chronic emphysema).
