If the fallen tear was not made lustrous by the thought of your teeth, then how did it turn into such a priceless pearl?

Here, the poet plays delightfully with the classic image of the beloved's teeth gleaming like precious pearls. He playfully reasons that his falling tears could only have gained such breathtaking radiance and turned into priceless pearls because they were steeped in the memory of that dazzling smile. The beauty lies in the word 'aab-dar', which cleverly means both liquid-soaked and brilliantly lustrous. It tenderly shows how the touch of true love transforms ordinary sorrow into something radiant and invaluable.
