I think that, in-universe, someone who is not in the know about the Sinclair-Valen connection should write a serious sociology paper on the ways in which Minbari religion is astonishingly like certain Earth religions, and how this proves something deep and meaningful about the universe and consciousness across species.

YES. I feel like there's a lot to be made of parallels between Buddhism and the Minbari religion as well. I kept waiting for the other shoe to drop, re: Sheridan's youthful obsession with the Dalai Lama.
