The poet says that he has never heard of such a sick and frail heart whose suffering's depth anyone could understand.

In this couplet, Mir Taqi Mir speaks of a profound, almost unique suffering that transcends mere description. He claims that his heart is so fragile and worn out that its depth of pain is incomprehensible to anyone else. This isn't just sadness; it is a declaration of a solitary emotional burden. It beautifully captures the poet's signature melancholy and deep self-awareness.
