The bitter floods of tears from my eyes fall, gushing; And they drain my dry, dry bones and skin.

This couplet paints a vivid picture of deep sorrow. Imagine tears not just falling, but gushing out like a roaring, salty waterfall from your eyes. The poet describes these bitter tears as so overwhelming that they feel like they're seeping deep into their very being, affecting their dry bones and skin. It's a powerful way to express a grief so profound and consuming that it feels like it's dissolving you from within, touching the core of your existence, leaving nothing untouched by the intense pain.
