From what I’ve read, the seeming light-at-the-end-of-the-tunnel isn’t always just a Catholic candle. To some people it’s a Mosque-lamp, a Menorah, or even stage-light from some huge revival-type religion-thingy.
The point is: Near-death experiences don’t point to some absolute, universal-truth, but instead to the preferences of the individual.
So ultimately, if what we regard as “heaven” is more similar to some pre-programmed, biological movie theatre than a narrow-gate…
**isn’t it possible that the very origin of the very idea of heaven was the result of some ancient near-death-experience that ultimately meant nothing more than contradictory good-feeling-nonsense?
