Kind of related to what I was mentioning on the Godel thread, but IMO the Kundalini (or whatever you call it) experience is the "grand unifying theory" of religion and mythology (although it's not actually a theory, but an experience).

It provides an explanation for where religions may have come from, beyond our typically pompous attitude that earlier generations of people were superstitious and stupid. Instead, it suggests that the founders of religions experienced dramatic shifts in consciousness which they were trying to explain in the language of the day (and which, since their followers rarely had such experiences themselves, were subsequently misinterpreted).
