Native American spirituality I do lean towards where we are connected to nature and earth. I also like Greek mythology and find it very interesting. Wiccan is another one that intrigues me a lot.
Zeus. No question.
His pantheon can come along too. If there is a god it’s going to be as ridiculous as the humans it controls.
I like Shamanism in the Americas ala Carlos Castaneda even though I know that it's exaggerated and fictionalized. What religion isn't?
I'm a Subgenius in my spare time. Seems like my time is always spare though. It doesn't seem to get in the way of my Devout Agnosticism, though...I can always bobbity bobbity bob bob to the beat without hearing the rhythm, if you get my rift.
I've been drawn to Norse mythology and I'm pushing to study more of it. The gods come off as reckless and bold. They're strong and not excluded from being "human". Same goes with Greek and Roman gods. No one has to pretend that they're perfect. No one cares if someone despises them. Just pray to another god to back you lol. But having already studied the Greek gods, I'm more familiar with those stories. I'd probably have to pick Greek mythology for that reason.
Tolkien's early works were based on Norse mythology. His story of Turin Turambar was based on the Finnish tale of Kullervo.
