Become.

It is not yet enough to have memories. One has to be able to forget them, if there are a great many, and one must have great patience, to wait for their return. For it is not the memories in themselves that are of consequence. Only when they are become the very blood within us, our every look and gesture, nameless and no longer distinguishable from our inmost self, only then, in the rarest of hours, can the first word of a poem arise in their midst and go out from among them.

Rainer Maria Rilke
