The feel of not to feel it, When there is none to heal it Nor numbed sense to steel it, Was never said in rhyme. - John Keats

I still don't know how to work out a poem.

A poem needs understanding through the senses. The point of diving into a lake is not immediately to swim to the shore, but to be in the lake, to luxuriate in the sensation of water. You do not work the lake out, it is an experience beyond thought. Poetry soothes and emboldens the soul to accept the mystery.

Philosophy will clip an Angel's wings,
Conquer all mysteries by rule and line,
Empty the haunted air, and gnomèd mine — Unweave a rainbow, as it erewhile made
The tender-person'd Lamia melt into a shade

I made a garland for her head,
And bracelets too, and fragrant zone;
She look'd at me as she did love,
And made sweet moan.
