O claw of madness, even if no thread of the collar is left around my neck to tear, the thread of breath still remains.

In classical Urdu poetry, tearing one's collar is the iconic symbol of absolute madness in love. Here, the poet converses with the personified 'claw of passion', noting that while his clothes are already shredded down to the last thread, madness need not despair. The fragile 'thread of breath' still lingers in his throat, readily offered up to be torn apart—showing that this love will settle for nothing less than total annihilation.
