For today, from Annie Dillard's Pilgrim at Tinker's Creek:
"Hasidism has a tradition that one of man's purposes is to assist God in the work of redemption by 'hallowing' the things of creation. By a tremendous heave of his spirit, the devout man frees the divine sparks trapped in the mute things of time; he uplifts the forms and moments of creation, bearing them aloft into the rare air and hallowing fire in which all clays must shatter and burst."
That describes the artist's job to me.
And when the work is going well, "My mind branches and shoots like a tree."
