Night and Day

[Pious Baloney]

I wonder if you truncated the first 4-lines to two whether that would take too much away from your piece. The lion's share of your poem has good flow and rhyme to it...except at the beginning and end. As a reader...this occurring at the end isn't as distracting as at the beginning. Perhaps instead of the first 4-lines as is...just keeping the part that rhymes:

'I am the night.'
'You are the light.'

Then proceed with the poem as is thereafter.
