Generally, Thelema symbols derive from a religion based on Thelema philosophical law. This law states that “Do what thou wilt shall be the whole of the Law. Love is the law, love under will” and was conceptualized by an English writer named Aleister Crowley in the early 1900s.
The symbol above is referred to as the Unicursal Hexagon and is the most important symbol of this religion. Though widely used by Aleistar, this symbol is believed to originate in 1639 having been developed by Blaise Pascal. It represents the five elements (pentagrammatic) as well as the heavenly cosmic forces.
