When this settled upon my heart, I accept the misery with joy.

This profound couplet speaks to the agony of deep, consuming love. The poet, Mir Taqi Mir, describes a situation where the beloved's presence has settled on his heart. The irony is that even when he is happy because of this love, that happiness itself feels like a torment. It suggests a passion so intense that it borders on pain, making mere joy unbearable.
