The Open Gates of Mysticism

Heavy use of drugs is an important part of Thelema rituals. Aleister Crowley himself had problems with addiction during his life. His heroin addiction came to dominate his life, and cocaine began to erode his nasal cavity. This collection presents Crowley's experiences with drugs with special emphasise on connection to spirituality and religion. Musaicum Books present his works on this subject:
