O heart, the beloved's pleasure is conditioned upon pleasing the rival; by no means can this unbearable burden of love be carried.

Here, the poet confides an unbearable dilemma of love to his own heart. The beloved's happiness comes with a cruel condition: the lover must accept and cater to the pleasure of the rival. While the heart can endure endless sorrow, rejection, and sacrifice for beloved's sake, swallowing one's self-respect to appease a rival is a burden far too heavy for any lover to bear.
