Robert Penn Warren said this quote
“ So there are two you's, the one you create by loving and the one the beloved creates by loving you. The farther those two you's are apart the more the world grinds and grudges on its axis. But if you loved and were loved perfectly then there wouldn't be any difference between the two you's or any distance between them. They would coincide perfectly, there would be perfect focus, as when a stereoscope gets the twin images on the card into perfect alignment. ”
