As soon as you get away from actual poetic forms, rhyme, meter, etc., there is no line between prose and poetry. From my way of thinking, many poets are simply lazy prose writers.
“It is always hard like this, not having a world, to imagine one, to go to the far edge apart and imagine, to wall whether in or out, to build a kind of cage for the sake of feeling the bars around us, to give shape to a world. And oh, it is always a world and not the world.”
William Bronk
