The path to mystical attainment or enlightenment was initially developed by Crowley largely based on the meditation/mystical techniques found in Buddhism and also the Tree of Life, especially as it was examined by Eliphas Levi in the 19th century and later by various members in the occult society, the Golden Dawn. In 1904, Crowley claimed to have transcribed, via "direct-voice transmission" from a "praeternatural intelligence" named Aiwass, The Book of the Law, which he eventually called the central sacred text of Thelema, heralding a new Aeon for mankind.
