MatthewJ1, regarding Belial, this discussion of references to him in the Dead Sea Scrolls and then the very brief discussion of references to him in the Book of Jubilees is illuminating:
Belial in Dead Sea Scrolls and Book of Jubilees per Wikipedia
To be honest, I don't like the air/fire/water/earth template for understanding Lucifer, Satan, Leviathan, and Belial, respectively. It forces our thoughts into unnecessary boxes. However, that being said, your analysis of Leviathan as the unconscious and Lucifer as consciousness is useful. We could then make Satan and Belial into reality and unreality (deception), respectively, bearing in mind that reality is the all in all, encompassing objective and subjective, conscious and unconscious, fact and falsehood, for even subjectivity and falsehood have their places in reality.
But I don't actually think in those terms. I'm not someone for whom TSB is so fundamental that it structures my philosophy. TSB was an appetizer, a preamble, a trailer for the movie.
For me, Satan is the more general, Lucifer the more specific. I use Satan as a symbol for the entire Left Hand Path in all its permutations. He rules it all. But he doesn't rule it alone. He is the Lord of Hell, and under him are many legions.
The foregoing paragraph illuminates my rationale for giving Satan the most general of assertions: "Fulfill your desires."
Lucifer, meanwhile, I give my incantation from the OP. Lucifer is the personification of the adept. That's why I also give him the Luciferian Rede, for which my muse and mentor was Baphomets. I attach it here, because it has a place in this thread.
