Thats a choice worthy of asking “Why” which your answer was “I don’t know.”

And "I don't know" is a perfectly valid response when we're dealing with things that are inherently mysterious and touch on the Ineffable which is beyond human understanding.

"I don't know" is the beginning of wisdom, not the end of it.

So if there's no meaningful separation between the Divine and anything else, why can't someone choose to view the idea of a celebrity as a gateway to the Divine if that Divine is both within and beyond our full understanding?

I could've chosen a tree or a river or the concept of "Love". It could be literally anything so it may as well be a celebrity because, ultimately, what's the difference from a non-dual viewpoint?
