The inspiration for my selection of today’s quote, the final lines of a poem, will be clear upon completion. (For some, the above photo might be a more immediate giveaway). The full poem, one of my three all-time favorites, is, alas, not acrosticizable (?)

If you’re not familiar with the work, you can read it in its entirety here after completing the puzzle.

[A note of special thanks to Jeff Linder, who spotted a glitch in my first iteration of this puzzle!]
