'cunning demons that wait
to violently strangle me
in surrounded darkness.'
^I think this could be better worded -- surrounded darkness threw me off. How about this --

'cunning demons that wait
to violently strangle me,
immersing me in darkness.'
^Just a suggestion

'Shall I ever climb a rainbow?'
^That's a great question & a great way to phrase your thoughts in an original way.

'I am going fully blind
ignorant to any guile
give back my sight kindly
so I won't be neglecting
wise and just prudence.'
^Did not like this stanza, it caused me to undergo a lot of confusion--could have just been me too. First line-- I am going fully blind -- where are you going? I didnt feel this was the strongest line either, could use some clarification. Also insert a comma after blind to separate the fact that you are 'going fully blind', ignorant to any guile... 'give back my sight kindly' -- rephrase as 'give my sight back kindly' --this sounds better to me. Also, I didnt like that line cause it caught a lot of confusion as well, I just think you could have reworded the whole stanza all together, I am completely & utterly lost dear...sorry. Could be the time of day that I'm reading this. 'so I won't be neglecting wise and just prudence' - just prudence? I thought you meant to say wisdom instead of wise but I think that goes along with prudence. I thought 'so' needs some work, its not really poetic at all.

The ending two stanzas made a lot more sense & seemed to really bring the poem together & your thoughts -- I just got a ltitle lost in the middle. Your title is beautiful & reflects your poem wonderfully.
