Thelema is the Greek word for Will and refers to the magickal and religious system discovered (renewed ?) by Aleister Crowley. Crowley (Master Therion) believed he had received a revelation from the god Horus (The Book of the Law) and using this reformed the Golden Dawn system he had received. As time when on this new form of magick became unique in its own right. After initiation into the semi-masonic Order of the Temple of the East (O.T.O) he promulgated his Law of Thelema and many O.T.O lodges accepted his revelation. Accordingly Thelema comprises many elements of earlier magical systems including Golden Dawn, OTO, Sexual Magic (Tantra) and many others. At his death there was no clear outline of successor and conflicts erupted over who should have authority, they continue to this day with a passion !
