Oh beloved, why should I not wander away? This time of sorrow has consumed my heart.

This couplet captures the profound agony of love's sorrow. The poet asks why he shouldn't just wander away, like a cloud or a candle flame. But the pain of grief, the sorrow itself, has already consumed his heart! It suggests that the suffering is so deep, it has become an inseparable part of his being, making escape impossible. A beautiful portrait of heartbreak's permanence.
