Like a drop of quicksilver, due to the movement and restless trembling of my heart, my beloved's heart has also gradually become restless.

The poet uses the striking image of a drop of mercury (quicksilver), which trembles at the faintest vibration, to describe how love spreads. Through the relentless yearning and beating of the lover's heart, the once-indifferent beloved has slowly caught that same restless rhythm. It is a tender reminder that true love doesn't conquer all at once; it gently transmits its own ache, softening the beloved's heart bit by bit.
