What kind of longing was in your gaze, Meer, that we cried so much after your departure.

This couplet is a beautiful lament on the pain of separation. Mir Taqi Mir is questioning the very intensity of his own gaze, suggesting that the mere act of looking at the beloved created such deep yearning. The tears that followed her departure are not just for her leaving, but for the overwhelming emotional state that her presence—and subsequent absence—induced! It's a perfect depiction of the agony of love.
