I'm trying to find an adjective to describe something - a thing, concept or idea - that transcends the empiric "mortal" world and exists in the afterlife. Specifically, the word should describe the object as not just existing simultaneously in both worlds, but also bridging the gap between them.
To give an example of such an object, love could be considered this, since sometimes even after a loved one dies the love between the two people still exists.
Any ideas? I'm stumped. I feel like there's a really good, simple word to convey this feeling that I'm just overlooking because it's 2:30 A.M. right now and I literally can't think.
