This is entirely the work of beauty and love, so whom else can one suspect or blame? Their temperament does not agree, nor does our heart align with them.

This couplet gently smiles at the timeless tussle between the lover and the beloved, pointing out that their discord isn't anyone else's fault—it is woven into the very fabric of romance. Beauty naturally brings aloof pride, while passionate love carries a stubborn, restless longing, making it impossible for their temperaments to ever settle in easy harmony. Instead of placing blame, the poet accepts this sweet friction as the inevitable and poetic truth of being in love.
