There is the following lines in the movie:-What am I trying to think of?
-There's this poem by Goethe
-Yeah, Goethe
-It's about two people who come from different places, but they hear the same bird singing.
"Perhaps the same bird echoed through both of us yesterday, separate, in the evening"
-That's it Exactly
-WowIt would appear the poem isn't really by Goethe but by Rainer Maria Rilke. Why the movie gets it wrong, I don't know.
--You Who Never Arrived--
You who never arrived in my arms, Beloved, who were lost from the start, I don't even know what songs would please you. I have given up trying to recognize you in the surging wave of the next moment. All the immense images in me -- the far-off, deeply-felt landscape, cities, towers, and bridges, and unsuspected turns in the path, and those powerful lands that were once pulsing with the life of the gods-- all rise within me to mean you, who forever elude me.You, Beloved, who are all the gardens I have ever gazed at, longing. An open window in a country house-- , and you almost stepped out, pensive, to meet me.
Streets that I chanced upon,-- you had just walked down them and vanished. And sometimes, in a shop, the mirrors were still dizzy with your presence and, startled, gave back my too-sudden image.
Who knows? Perhaps the same bird echoed through both of us yesterday, separate, in the evening...
