As I've mentioned before, C.S. Lewis' theories have greatly helped my research for this story, more so the heavenly than the earthly. At first he made my ideas seem so ordinary and not even close to what I was really trying to attain. But then I realized that it is not possible to accurately depict the heavenly things. Because no eye has seen and no ear has heard, and no mind can conceive, it's only natural that my imaginings are according to my own understanding. As a dog can't comprehend things as a human can, so a human can't comprehend things as an angel might. That was the first profound discovery.
The second was that the New Earth cannot be all that different from what we know now, only completely pure. Human beings, even human souls, must have an environment for communicating. I had a theory that disembodied spirits could have some form of telepathy in which they communicate--and that may still be true. But if we're going to have glorified bodies one day, then we are surely going to need a glorified location in which we live.
