Juan Farfan's "Para Una Reina" is a passionate declaration of love and admiration for a woman he calls the "queen of the plains." He's completely captivated by her smile and natural charm, saying she conquers the Colombian towns with her presence. He feels her love has been a "convent that imprisoned his chest" [tu amor ha sido un convento que aprisionaban y techo], meaning it's been a powerful, almost overwhelming force that he can no longer keep silent about.
He sees her as the most beautiful among queens, praising her nobility, generosity, and how she treats others. He wants to be the owner of her body and the sweetness in her gaze, boldly stating he wants to kiss her and make her his wife to love until the end. He can't stand being alone anymore, dreaming of her beauty and wanting to rest by her side. He asks why she can't be the queen of all his love, just as she's the queen of the plains, because he admires her in his dreams and wants to see her in person. He's so in love, he's asking for her hand in marriage, even if he's just her admirer.
