Sure brother, but a lot is my conception, that's the point of esotericism, the gnosis of divinity.
I'll give you the academic sources though.
Western Esoteric Traditions by Clarke
-best I troduction there is and probably what you're looking for.
Corpus Hermeticum
-The cornerstone of Western Esotericims
Gnostic Texts
-A good understanding of Gnosticism is important.
Plato/Plotinus
-there's too much to say, but understand the theory of Forms and the transmigration of the soul
Augustine
-He applies the Platonic view to Christianity and forever changes western theology.
Jung
-modern master, once again too much to say, but start with "Man and His Symbols."
-understand archetypes, collective unconscious, active imagination.
Joseph Campbell
-Hero with a Thousand Faces, a continuation of the Platonic truth as manifested in myth. All stories are one, the Perennial Philosophy.
-Alchemy, Astrology, Greek and Egyptian Myth is good, Christianity, Gnosticism, a good bit of Eastern thought.
-Theosoohy is alright with Blavatsky.
-You'll run into a fair bit of Crowley in this line of thought so it's good to be familiar with him.
That's a good basis achademically speaking. But like I say, you gotta experience it or it's just words on a page.
