Longing is painful. Every work of art is an attempt to bring into being the object of loss. The pictures, the music, the poems and the performances are an intense engagement with loss. While one is in the act of making, one is not in loss, and one has meaning. The fierce crashes that happen to many creative people when a piece of work is done (read Hemingway on this) come out of the sense that however good the work, it has not answered the loss.
