Thelema is an esoteric and occult social or spiritual philosophy and religious movement developed in the early 1900s by Aleister Crowley. The Thelemic pantheona collection of gods and goddesses who either literally exist or serve as symbolic archetypes or metaphorsincludes a number of deities, primarily a trio adapted from ancient Egyptian religion, who are the three speakers of The Book of the Law: Nuit, Hadit and Ra-Hoor-Khuit. This book thoroughly explains thelemic belief system which is synthesised from many sources, including Eastern Yoga, Hermeticism, medieval grimoires, contemporary magical theories from writers like Eliphas Levi and Helena Blavatsky, and Crowley's own original contributions. Aspects of Thelema and Crowley's thought in general inspired the development of Wicca and, to a certain degree, the rise of Modern Paganism as a whole, as well as chaos magick and some variations of Satanism.
