It doesn't build (a life) for us by going to his house, so do not return. One day, our blood will spill upon that dust.

This profound couplet speaks to the irreversible nature of deep emotional experience. Mir Taqi Mir suggests that once you walk through the streets of a beloved, the memory and impact are permanent. It's not just about leaving; it's about the stain left on your soul. The final line, 'Our blood will fall upon that dust one day,' means that the pain, the struggle, and the love poured into that place will eventually be recognized and remembered forever.
