Haha well I'd say Leviathan eats everything. Therefore Leviathan is The All. Therefore The Absolute is in the abyss of mind, and internal searching (The LHP) is the inclusivistic way to spiritual perfection. The thing is, this does not make sense: Leviathan being The All. The abyss would be The All, and I have no idea where Leviathan stands.
Look:
Satan - The Adversarial power. The rebellion.
Set - The power of Being / Xeper. Becoming your true Self.
The Abyss - The infinitely deep, chaotic waves of the mind. Accessed through the above, it leads to:
Baphomet / Lucifer - A perfect being. Perfect balance, mastery of philosophy, mastery of self, etc etc etc.
Leviathan would fit between The Abyss and Baphomet / Enlightenment. I feel it is the Kundalini serpent of Hinduism. An eternal and ancient power that rests inside each spiritual being and, once released, is an unstoppable force of True Will. So pretty much Leviathan is the Kundalini serpent is what I am saying... haha. Sorry, that is kind of obnoxious rambling.
