Firstly, I didn't read through everything, just thought I'd drop in my position.
As a theist-agnostic, through my life's experiences I've felt a sort of contact with the divine, whatever it may ultimately be. In particular, I had a very intense moment in which I can only describe myself as having "Momentarily achieved Nirvana." As soon as I noticed, it was gone.
Anyhow, I couldn't justify taking part in a particular religious practice "just in case." Seeing what I've seen, feeling what I've felt, all my life experiences lead me to believe that if there is something otherworldly out there, it's beyond my scope of definition. Being unable to satisfactorily identify "what lies beyond," all I have are my life experiences, which include a limited -- though far more thorough than most truly religious individuals -- self-education of various practices and beliefs. All I can say is none of it feels right. All that feels right is living my life as positively as possible.
One thing I've told a Christian friend is, I don't pray, I just work for what I want or need... Which is exactly what you do, but I take credit for achieving goals instead of giving it away. Some may call it Hubris, I suppose, but I need a deity as much as a deity needs me.
I hope this is clear, I've low on sleep and full of Mountain Dew. I'll cut it there before I end up writing an essay.
Edit: I forgot to mention yesterday that I was NOT, in fact, taking any drugs in the aforementioned experience. I don't do anything mind-altering/expanding/muddling/what-have-you, so in case you were wondering, there ya go.
