Aesthetics is concerned with form, shape, composition, expression, and seeing forms AS THEY ARE. Just as the artist is "inspired" and filled with enthusiasm, so too those who SEE are seized with the divine spirit. What is seen is the doxa (glory) of the form, but this glory is the glory of being. Balthasar argues that the mystery in such beauty is the interruption of the eternal into the material in such a way that one can speak of the event of beauty, the entrance of the numinous into this world. To see beauty is to be overcome by the glory that breaks out of this person, this poem, this picture, this flower... We are confronted by the sense of its Otherness.
Because in trying to articulate what, perhaps, joy is, it has occurred to me that among other things—the trees and the mushrooms have shown me this—joy is the mostly invisible, the underground union between us, you and me, which is, among other things, the great fact of our life and the lives of everyone and thing we love going away. If we sink a spoon into that fact, into the duff between us, we will find it teeming. It will look like all the books ever written. It will look like all the nerves in a body. We might call it sorrow, but we might call it a union, one that, once we notice it, once we bring it into the light, might become flower and food. Might be joy.
