In the quote from Peter S. Beagle's "The Folk of the Air," the speaker emphasizes the uniqueness of an individual by comparing them to celestial bodies. The phrase suggests that just as there are no two stones alike in the sky, each person holds a distinct value and beauty that sets them apart from others. This reflection evokes a sense of wonder and appreciation for one's individuality, regardless of any imperfections.

By identifying a person as a "wonder of the cosmos," the quote underlines the idea that everyone has inherent worth and significance in the grand scheme of the universe. It encourages embracing one's uniqueness and highlights that feelings of embarrassment or insecurity don't detract from one's value. Ultimately, it is a celebration of the remarkable qualities that make each person special.
