What about nature as the actual source for concepts re-applied?
Now in the darkness of the night the many stars are visable, the 'lights" of the heavens, along with the moon who has a pagan tiltle as Mother Moon.

That natural event is simular to the transformation from poly to mono if you can vision the anology relative to religious concepts.
