The eyelid, like a star's gleam, has blinked, for the sake of battling those stubborn, harsh nights.

This profound couplet speaks to the devastating power of a single glance or wink. Mir Taqi Mir suggests that the mere blink of those mesmerizing, starlit eyes (चश्म-ए-नजम) is enough to provoke deep emotional turmoil. The poet implies that the beloved's casual gesture—a mere wink—is the sole reason for the lover to engage in such painful, difficult struggles. It's a masterful portrayal of how beauty can be both the cause and the source of unending heartache.
