From the dust-bath of the world, 'Mir', we have lost our senses; / Our grime is so deep that we weep into the earth.

This couplet speaks to a profound, almost existential weariness. Mir Taqi Mir is telling us that the superficial dust and troubles of the world do not disturb him. His grief is so deep, so overwhelming, that his sorrow makes him weep into the very earth itself. It's a beautiful declaration of internal suffering that transcends worldly pain.
