I've never understood this thing about finding a god to fit the individual other than it being proof god is manmade.
What it is about is the individual seeking Liberation, or Enlightenment. How someone needs to see or frame the Divine for themselves, whatever forms or paths that needs to take for them, is a sort of dance between themselves, and the Divine they seek.
Yes, ideas we have about the Divine, what can be called by many names, like God, are man-made, in the sense that they are images from our minds. But they are images inspired by the heart, whose purpose is to open us to connection with the Absolute. The quest is to see beyond the symbols into an Awakening, or Realization of the nature of existence itself, or God.
Because we all have different histories and personalities and experiences, there never truly can be a one-size fits all solution. Like climbing a mountain, you have to be adaptive. The tools we come up with to help us do that, can be said to be "man-made", but the desire to climb that mountain itself, is not. That, in my view, is the Divine within us, urging us to figure out how to get up there. That's not man-made. That's Ground. That's Source.
