10. Ordo Templi Orientis
One of the most famous members of this secretive group is the madman Aleister Crowley. Frequently labelled as a cult, the Ordo Templi Orientis is also related to the Gnostic Christian Church, which happens to be one of their branches and practices the Law of Thelema. The Law of Thelema in its essence is the belief that ‘one should do as they will’ or ‘do what thou wilt’. It is basically the right to live life the way someone prefers to, whether it be eating, drinking, dressing or whatever other activity and not to interfere with others who are doing the same. But of course, there is a lot more symbolism and theology to that.
