Now madness itself is clutching at the collar, and that old custom of formalities and polite restraint is completely gone.

In Urdu poetry, clutching or tearing one's collar is the classic sign of passion running wild and untamed. Here, the poet says that his inner frenzy has taken complete control, sweeping aside all the polite masks, etiquettes, and restraints demanded by society. It captures that honest, vulnerable moment when emotion becomes so overpowering that pretending to be composed is no longer an option.
