We wouldn't need the word "prose" if it weren't for poetry.
One must have a mind of winter.
I believe that to read poetry, one must have a mind of poetry. You must enter a state where you come to understand meaning-resistant arrangements of language as having their own kind of meaning. It’s quite similar to those Magic Eye posters from the ‘90s: If you haven’t figured out how to look at them, you can’t believe that anyone really sees the dolphin. (This metaphor has its limits, making learned skill seem like an on/off conversion; too, with poetry, even when you’ve mastered “the trick,” not everyone sees the same thing.)
