The only way a work of art can become great is for one to acknowledge that it doesn't belong to anybody. The greatness is in constantly giving back, coming to an acknowledgment of the source. Look back to the source of any individual, any process, any set of materials. If the individual personality can relinquish its insistence on concepts like this is mine, I did it, this is original, nobody else has done it, it goes straight for greatness or the essential spirit.
