After his departure, I, who was enchanted by him, could not even fathom what had happened to my heart.

This profound couplet captures the total devastation caused by separation. Mir Taqi Mir suggests that the beloved's departure was so devastating that it didn't just wound the heart, but it completely drained the poet's very life force and strength. It speaks to a loss so immense that the poet himself was unaware of the depth of the emptiness, making it a timeless cry of existential despair.
