Tears have flowed from my eyes day and night, and now the entire city is immersed in rain.

This couplet is a profound piece of poetic introspection. Mir Taqi Mir beautifully equates the depth of personal sorrow with the natural world. He says that his tears have flowed constantly, day and night, and now the entire city is raining. It's not just a coincidence; the external rain is a reflection, a physical manifestation of the unbearable grief that has drained the poet's soul. It speaks to a sorrow so deep it cannot be contained.
