It is the harmony of the diverse parts, their symmetry, their happy balance; in a word it is all that introduces order, all that gives unity, that permits us to see clearly and to comprehend at once both the ensemble and the details.
Have you ever looked up at the stars and felt, simultaneously, that you were a part of something huge and also a speck of nothing? With a perspective of our relative importance, we can balance our sense of self-worth with our actual value in the world. We DO have a role here and it fits into the big scheme of things. But, truthfully, we are but atoms vibrating together.
All atoms on our earth and within our atmosphere available to us are finite in number. Carbon atoms may be here as carbon dioxide or carbohydrate or as a myriad of things, but there are no new atoms being made (with apologies to my physics friends who know there are a few minor exceptions which do not impact this discussion). When the earth was formed, it was comprised of all the atoms that would exist here and they keep cycling through our world as different molecules. In that respect, the Creation Story is accurate; when the earth was finished, that was it, as far as creating new atoms.
So, what is your mission, as a collection of finite atoms on this earth? Are you living it?
