What is the reason, 'Meer', that we see some trace of sorrow on your face?

This profound couplet captures the intimate pain of observation. The speaker is asking the beloved: 'What is the reason that we see such regret on your mouth?' It is not a question of blame, but of deep, empathetic sorrow. The poet, Mir Taqi Mir, highlights how even the slightest emotional nuance of the beloved—a visible trace of sadness—is enough to pierce the lover's heart. It speaks to the painful intimacy of knowing another person's hidden grief.
