Thanks for sharing these and reminding me I need to go back and re-read Rilke. It has been a while. (Incidentally, given my translation board posts, Hölderlin was a pretty big influence on Rilke).
Some writers you come across at just the right time and moment for them to have an impact. Cummings in high school, and then Keats and Rilke were it for me in college. I've come back to Cummings occasionally and he doesn't really do it for me in the same way. Keats and Rilke, though I've only dipped my toe in occasionally since, still take the top of my head off.
