Thelema is a Western esoteric and occult social or spiritual philosophy, as well as a new religious movement that was founded in the early 1900s by Aleister Crowley (1875–1947), an English writer, mystic, occultist, and ceremonial magician. Central to Thelema is the idea of discovering and following one's True Will, a unique purpose and calling that goes beyond ordinary desires. Crowley's system begins with The Book of the Law, a text he said was dictated to him by an entity named Aiwass. This foundational work lays out key principles, including the central axiom "Do what thou wilt shall be the whole of the Law". This principle emphasizes personal freedom and the pursuit of one's true path, while being guided by love and finding one's authentic purpose.
Liber AL vel Legis, commonly known as The Book of the Law, is the central sacred text of Thelema. Aleister Crowley said that it was dictated to him by a beyond-human being who called himself 'Aiwass'. Rose Edith Kelly, Crowley's wife, wrote two phrases in the manuscript. The three chapters of the book are spoken by the deities Nuit, Hadit, and Ra-Hoor-Khuit.
Ordo Templi Orientis is an occult secret society and hermetic magical organization founded at the beginning of the 20th century. The origins of O.T.O. can be traced back to the German-speaking occultists Carl Kellner, Theodor Reuss, Heinrich Klein, and Franz Hartmann. In its first incarnation, O.T.O. was intended to be modelled after and associated with European Freemasonry and as such in its early years only Freemasons could seek admittance.
The Holy Books of Thelema is a collection of 15 works by Aleister Crowley, the founder of Thelema, originally published in 1909 by Crowley under the title Θελημα, and later republished in 1983, together with a number of additional texts, under the new title, The Holy Books of Thelema, by Ordo Templi Orientis under the direction of Hymenaeus Alpha.
The A∴A∴ is a magical organization described in 1907 by occultist Aleister Crowley. Its members are dedicated to the advancement of humanity by perfection of the individual on every plane through a graded series of universal initiations. Its initiations are syncretic, unifying the essence of Theravada Buddhism with Vedantic yoga and ceremonial magic. The A∴A∴ applies what it describes as mystical and magical methods of spiritual attainment under the structure of the Qabalistic Tree of Life, and aims to research, practise, and teach "scientific illuminism". A∴A∴ is often held to stand for Argenteum Astrum, which is Latin for Silver Star; however, see the section on Name below.

Heru-ra-ha is a composite deity within Thelema, a religion that began in 1904 with Aleister Crowley and The Book of the Law. Heru-ra-ha is composed of Hoor-paar-kraat and Ra-Hoor-Khuit.

Their stelae link Nuit and Hadit to the established ancient Egyptian deities Nut and Hor-Bhdt.
