All my senses, patience, pride, and power departed, but you, O stain of the heart, did not leave.

This profound couplet speaks to the enduring nature of deep emotional wounds. The poet observes that everything temporary—our senses, our patience, our worldly charms, and even our strength—all fade away. Yet, the 'daagh' (the stain or mark) of love, the emotional scar left on the heart, remains forever. It highlights that some wounds are not physical, but deeply imprinted on the soul, defying time and circumstance.
