"...I do not experience this. A shade of grey, to me, simply looks grey no matter what it is next to. I do not perceive the optical illusions that humans do. I see things with great clarity and wholeness. I could compare a shade of grey to the colors nearby and thereby judge it subjectively. But such thinking does not come naturally to me. It sounds as if, to you, it is as natural as breathing.
And I have noticed too that mortals do not oft see the future implications of a thing, the patterns that it forms. When I observe a mouse enter a chimney, I know immediately the immense confluence of things that has led to this, how the mouse acts according to its nature and is influenced by weather, other beasts, human action, and chance, and the myriad small or large changes it can bring, though which possible changes will actually come to pass requires careful analysis. I do not think that would be natural to you.
This, I believe, is why God had chosen to create mortal-born angels. That host had differing strengths and specialties, and differing failures and weaknesses, than the heaven-born."
