If that voice that you created that is most alive in the poem isn't carried throughout the whole poem, then I destroy where it's not there, and I reconstruct it so that that voice is the dominant voice in the poem. ↗
My sense of a poem - my notion of how you revise - is: you get yourself into a state where what you are intensely conscious of is not why you wrote it or how you wrote it, but what you wrote. ↗
