Franz Rosenzweig said this quote

“ Love is only surpassing sweet when it is directed toward a mortal object, and the secret of this ultimate sweetness only is defined by the bitterness of death. Thus the white peoples of the world foresee a time when their land with its rivers and mountains still lies under heaven as it does today, but other people dwell there; when their language is entombed in books, and their laws and customs have lost their living power. ”
