Before you know what kindness really is
you must lose things,
feel the future dissolve in a moment
like salt in a weakened broth. (…) Before you know kindness as the deepest thing inside,
you must know sorrow as the other deepest thing. (…) Then it is only kindness that makes sense anymore, (…) and then goes with you everywhere
like a shadow or a friend.
