How is poetry different than prose?

The divisions between poetry and prose aren't clear-cut, but here are some generally accepted differences. The language of prose is typically straightforward without much decoration. Ideas are contained in sentences that are arranged into paragraphs. There are no line breaks.

where is the writing? (so i can answer)

imparadis't in one anothers arms  

the happier eden, shall enjoy their fill  

of bliss on bliss, while i to hell am thrust,  

where neither joy nor love, but fierce desire,  

among our other torments not the least,  

still unfulfill'd with pain of longing pines;  

yet let me not forget what i have gain'd  

from their own mouths; all is not theirs it seems:  

one fatal tree there stands of knowledge call'd,  

forbidden them to taste: knowledge forbidd'n?  

suspicious, reasonless. why should their lord  

envie them that? can it be sin to know,
