Thanks for the spiritual support! Since "crossing the gnostic threshold of enlightenment" (or whatever you want to call this), I've been involved in a couple of esoteric mystery schools and am currently studying the Qabalah (I'm actually running a monthly Qabalistic study group at a Masonic temple right now, which is definitive proof that I never have any idea what I'll be doing with my life 5 years out).
If there is one thing that I have learned since I first started writing the first draft of this story many years ago, it's that reality is super weird and none of us will ever fully understand it. But equally weird was the revelation of what's possible to know from a human perspective -- specifically, that we are all literally experiencing fragments of the same one infinite consciousness (ie. Kether/Ehyeh/the One/the central "I am" presence within all of us), which is responsible for manifesting our shared physical reality.
For those who find that last statement ridiculous, my Past Self is right there with you, and that's the "center" from which God's Assassin was written. I remain of the firm stance that sincere truth-seeking counts for way more than whatever your current truth may be. Whether any of my writing resonates with you or whether it sounds like complete bullshit, nothing makes me happier than seeing people thinking for themselves and reaching their own conclusions about the nature of themselves and their own reality.
I wish you the best upon your own spiritual path -- I'm still not onboard with the exoteric Christian dogma of an anthropomorphic God separate from ourselves, but The Bible is still loaded with plenty of occult wisdom for anyone with eyes to see. :)
