O cruel one, if only I had control over your heart, no mischief or turmoil would ever manifest until the Day of Judgment.

Here, the poet playfully and tenderly blames the beloved's indifferent heart for all the chaos and heartbreak in the entire world. He sighs that if only he held sway over that stubborn, unyielding heart, he would pacify it, ensuring no strife or turmoil would ever rise again until the Day of Judgment. It is a charming romantic hyperbole that places the beloved's affection at the very center of cosmic peace.
