For the letter H, let’s focus on....
Yes, there is nothing like a “light” topic to kick things off again here.
Roughly speaking, heaven either means the physical sky or universe or it refers to an “afterlife plane of existence”. No, that doesn’t mean you’ll have to go through a soul security check and be served stale peanuts on your way there.
Heaven has so many meanings I could write an entire humor book on the subject. Of course, doing that would only piss off the entire religious world and I’d have to go into hiding for the rest of my life; oh wait, I rarely go out anyway…
Oh, and angels, what’s with the wings? What if I’m afraid of flying? Plus, how can you really play a fun game of naked twister in heaven if you’ve got these big bulky wings restricting you?
Now the mechanics of what is heaven, what you experience there and how it all works is completely subject to interpretation or simply made up. For example, I could write that heaven is made of pickles and is based on a pickle hierarchy. Wait several thousand years and somebody will take that literally or symbolically and worship pickles. And why shouldn’t we…those dills are quite good!
