And you seem to be describing a numinosity or a spiritual elevation when you describe knowing more even though something is beyond your faculties or ability.Why would God be necessary for there to be transendence? I don't find that empty at all. Transcendence is about the idea that existence is more than just what can know with our faculties. Strictly speaking, a multiverse (should there be such) transcends our universe and our universe transcends us both as individuals and as a species.
That's where spirit, if such exists, is to be found IMHO: In our experience of a reality bigger than ourselves. That needn't be supernatural, though. The complex universe (or multiverse if you buy into one of those hypotheses) is enough.
