The thought is that the eye that fell upon you has become a buyer, even by selling its life.

This profound couplet speaks to the intoxicating power of the beloved's gaze (nazar). The poet suggests that the pleasure derived from merely seeing the beloved's eyes is the greatest treasure. It is a delight so overwhelming, so addictive, that the lover would sacrifice their very life just to experience it one more time. It elevates the gaze from a simple look to a priceless, life-altering commodity.
