If I have a belief system outside of loose gnostic Luciferianism, it is Crowley's true will. Allow me to enlighten you with wikipedia.
The cult of Thelema: The religion is founded upon the idea that the 20th century marked the beginning of the Aeon of Horus, in which a new ethical code would be followed; "Do what thou wilt shall be the whole of the Law". This statement indicates that adherents, who are known as Thelemites, should seek out and follow their own true path in life, known as their True Will, rather than their egoic desires. The philosophy also emphasizes the ritual practice of Magick.
According to Crowley, every individual has a True Will, to be distinguished from the ordinary wants and desires of the ego. The True Will is essentially one's "calling" or "purpose" in life. Some later magicians have taken this to include the goal of attaining self-realization by one's own efforts, without the aid of God or other divine authority.
When a person does their True Will, it is like an orbit, their niche in the universal order, and the universe assists them. In order for the individual to be able to follow their True Will, the everyday self's socially-instilled inhibitions may have to be overcome via deconditioning. Crowley believed that in order to discover the True Will, one had to free the desires of the subconscious mind from the control of the conscious mind, especially the restrictions placed on sexual expression, which he associated with the power of divine creation.
Crowley describes the pursuit of Will as not only with detachment from possible results, but with tireless energy. It is Nirvana but in a dynamic rather than static form. The True Will is described as the individual's orbit, and if they seek to do anything else, they will encounter obstacles, as doing anything other than the will is a hindrance to it.
