The transition between faith to no faith.

[Whateverist]

Yet in this insanity, I felt I did see potential beauty, glory, and greatness but that these were archetypes that exist in me and is both imaginative but has some basis to reality. I don't know.

Perhaps a first step would be to acknowledge that all the experiences you've had were about your god. As you say your imagination along with whatever patterns come with our brains (archetypes) as well as all your acquired beliefs conspire to color your out of the ordinary experiences. They may apply beyond you, but you have no way to know that for sure. It may be that your god is not a dick about holding him above all others. Maybe He doesn't insist that he is anything more than your god. Next time you're in an altered state, try asking Him.

So you don't have to toss your god out on his ass. You can simply start envisioning Him as possibly being an aspect of you. Keep admitting you don't know and possibly can't know.

Also, give some thought to what you have to offer your god. You need to try to even the playing field. Your god may value having a relationship with you. Just get out of the habit of projecting him out into the world. Remember, you don't know where he is so don't be too quick to humble yourself. He gets respect but so do you. And everyone else gets respect as they wrestle with the same puzzle as you. They don't need you to proclaim the objective status of your god. They've got their own daemon to deal with.
