Hmm, I'm still not sure if I can grasp the nature of that world. So what if I do not want to ascend (and not descend either of course), but just to live my merry life on Earth, because I like physical things (like physical love, food, drink, a warm breeze in spring, etc.), and because I'm happy with what I have? Do I still have to be eliminated then, even if I never chose to harm anyone? You say it's not "black and white" or "good and evil", but the fact that I have to make progress by force (towards Astral and divinity) or be extinguished is pretty binary in itself. There are no other choices? Feels wrong to me. What about freedom?
So if I want to just live peacefully (and physically), I cannot, because some higher being will always murder me, no matter what I do or don't do. That's kinda... I dunno... I don't get it? So I have to become a god first, then create my own (virus-free?) world just so I can go back to square one and get myself a physical body to enjoy my skinship, meat and beer. ;) And this time, nobody will kill me, simply because I'm far too powerful?!
I just don't get this at all.
Is the virus in this now-godless world the key? If so: What *is* that virus? What is its nature? How does it infect people? When Rena and Ria come to Astral, they seemingly came from a very advanced world (she spoke about phones once?). That means humankind can't be just some mindless mob, they're a thriving high-tech civilization pursuing scientific progress, which doesn't have reaching divinity as a goal, even though it might result in such a thing at some point in time...
The whole concept is very hard to understand (and hence accept) for me. Maybe because of my cultural background, I don't know - I'm from Europe, which has a Christian background and I'd call myself a secular pantheist. Maybe I'm wrong, but parts of your concept remind me of Buddhism. Never liked Buddhism either, it eludes my value system. Like Buddhism teaches us to reach "ascension" by ridding ourselves from all desire. To me, ridding myself of desire would mean death. No desire - no fun - no life.
While Astral isn't the same, the ascension to it it has a similar concept of getting rid of a LOT to get there, even very important things. Maybe that's why I don't like it? Hm.
Ah, sorry for my ramblings, I hope this doesn't annoy you. ;)
