I'm not talking about spiritual insights, higher truths or the great sky mother, none of which I believe in. Hardcore materialist, remember?

If you don't believe in things that can't be explained sufficiently you must have some pretty bad problems with gravity. My point was meant to be precisely that sometimes things work even when we don't quite know why and even though there are all sorts of bizarre stories woven around them. Like gravity. I expect we'll eventually work out why they work, but we don't have to suspend belief in the fact of their efficacy because we don't know why they're efficient. Like gravity.
