Aleister Crowley was an English occultist and ceremonial magician. He was once known as “the wickedest man in the world.” Several decades after his death, he is still regarded as one of the most influential occultists of all time. Crowley led a life that was absolutely shocking given the time and era he lived in; he was a heavy user of recreational drugs and notorious for his sexual practices with individuals of both sexes. He joined the ‘Hermetic Order of the Golden Dawn’ as a young man and claimed to have been contacted by ‘Aiwass,’ his Holy Guardian Angel. He believed to be the prophet of a new age and played a significant role in founding a religion called ‘Thelema,’ which proposes that its adherents, known as Thelemites, should seek their own true path in life and follow it. Eventually, this philosophy came to be accepted by the ‘Ordo Templi Orientis’ (O.T.O.). Crowley went on to form his own occult society and later on created a religious commune called the ‘Abbey of Thelema.’ A man with a wide range of interests, he was also an avid mountaineer who scaled several lofty peaks all over the world. He led a highly controversial life and was also known as The Beast 666.
