Since I encountered the curtain of blood, my friends' sleeves have not remained pure.

This profound couplet speaks to the heavy burden of sorrow. Mir Taqi Mir suggests that since he has become entangled in the tragedy or 'curtain of blood' (giriya-e-khooni), his sorrow has stained the very companionship around him. It's a lament that true grief doesn't just affect the self; it colors the lives and relationships of those closest to us.
