If this surge of weeping continues, thousands of pieces of my heart will flow with my tears and appear in my moist eyes.

The poet paints a startling, almost physical picture of grief, imagining tears not as mere drops, but as a sweeping flood. He laments that if this torrential weeping continues, the shattered fragments of his broken heart will be dragged along by the tide and pour right out through his eyes. It is a poignant, unforgettable image of total heartbreak, where the sorrow is so consuming that the lover’s very core begins to dissolve into tears.
