For the sake of a line of poetry one must see many cities, people, and things, one must know animals, must feel how the birds fly, and know the gestures with which small flowers open in the morning. One must be able to think back to paths in unknown regions, to unexpected meetings and to partings one long saw coming; to childhood days that are still not understood, to parents one had to hurt when they brought one a joy and one did not understand it (it was a joy to someone else); to childhood illnesses that set in so strangely with so many profound and heavy transformations, to days in quiet, muted rooms and to mornings by the sea, the sea altogether, to nights travelling that rushed up and away and flew with all the stars; and if one can think of all that, it is still not enough.
