The days have passed when nights were cut from the drains; now the unsteady 'Mir'-sahib groans something.

This profound couplet is a classic example of nostalgic regret. Mir Taqi Mir is looking back at a time when his nights were spent wandering along the drains—a life of carefree, perhaps bohemian, existence. Now, he finds himself unsteady and groaning, realizing that the ease and freedom of those days are gone. It’s a powerful meditation on the irreversible passage of time and the pain of lost youth.
