Very cool, as much as I love the wealth and richness of where I settled, I think the primary thing is the recognition of the fundamental principle of monotheism that there's only one supreme power/creator/etc and that all stems from that.
On the level down, as I study Judaism deeper and esoterically, I find concepts that are conceptually aligned to concepts I found deep in Yogic tradition.
I think the primary divine spark is a man waking up and going "there's more to this, I want to connect to it emotionally and intellectually" -- that's the starting point of religion. Whichever path you take to explore that will end up in a conceptually similar place I think (at least based on these experiences.) Good luck!
