On the steel plate of my chest, my hundred arrows of letters strike, this is the reason my heart, broken, has become weary.

This profound couplet speaks to the deepest agony of the poet's heart. Mir Taqi Mir suggests that the pain of a broken heart is so immense that even his own verses—which he wields like hundred arrows—feel like wounds upon his chest. The constant suffering and the emotional exhaustion it brings are the true source of his weariness. It’s a powerful depiction of poetic suffering!
