And still it is not enough to have memories. One must be able to forget them when they are many, and one must have the great patience to wait until they come again. For it is not yet the memories themselves. Not until they have turned to blood within us, to glance, to gesture, nameless and no longer to be distinguished from ourselves - not until then can it happen that in a most rare hour the first word of a verse arises in their midst and goes forth from them.
