Famously known as 'The Wickedest Man in the World', Edward Alexander Crowley was born on the October 12, 1875. Devoutly known for his involvement in the occult, he was part of a number of magickal organizations, namely The Hermetic Order of The Golden Dawn, Argenteum Astrum or the A?A? (founded by him) and Ordo Templi Orientis. Crowley was born in a Plymouth Brethren family and the Christian faith was imposed upon him from a very young age by his father, a preacher back then. Only after the death of his father, did he start questioning the Christian faith and he soon earned a reputation as something of a rebel. He drew interest from many Eastern religions like Hinduism, Buddhism, Tantra and Zoroastrianism. Crowley later went on to form his own religious philosophy, which he called Thelema. Thelema was a combination of philosophical libertarianism, influences from the Golden Dawn and eastern influences like Kabbalah and Tantra. Crowley practiced Sex Magick, the use of sexual energies to form a base where rituals were performed. He believed that during an orgasm, an individual has the ability to reach a spiritual state, which one could not easily attain in a normal state of mind. Crowley had a fecund mind and wrote many books not only about the occult and Thelema, but even on philosophy and culture. His most famous books were The Book of the Law, The Book of Lies and The Confessions of Aleister Crowley, to name a few. He also wrote a number of poems and plays. A great chess player, Crowley beat many a chess champion during his childhood years. He gave up playing chess owing to a mystical experience, where he realized how insignificant his goal to be the world chess champion was. Crowley attempted to climb K2 on an expedition with Eckenstein, and broke the world record for living on a glacier for 68 straight days. He later attempted to climb Kanchenjunga in Nepal, the world's third highest mountain. Aleister Crowley died on the December 1, 1947 leaving behind a legacy for thousands of his followers and believers in the occult. His work and philosophies earned tributes from musicians like The Beatles, Jimmy Page and Ozzy Osbourne. Aleister Crowley continues to be a significant icon in popular culture to this day.
