Why would the stitches of the wound not snap? Just look at the injustice that the thread of my own torn collar was used to sew up the wound.

In Urdu poetry, tearing one's collar is the quintessential sign of love's madness and despair. Here, the poet reveals a tragic irony: the healer stitched his wounds using the loose threads from that very collar. Naturally, the moment the fever of love returns and he pulls at his clothes, the stitches are doomed to snap, ensuring his wounds remain perpetually raw.
