If the chest is bright, it is the burning passion of speech, O mirror of life; if it is not bright, then the speech is the path to eternal remedy, O cupbearer.

This powerful couplet speaks to the conditionality of art and truth. The poet addresses the 'Saqi' (cupbearer), stating that poetry's burning passion (saz-e-sukhan) can only be the essence of life if the heart (the source of truth) is illuminated. Otherwise, it is merely a path to perpetual death. It's a profound commentary on the necessity of transparency and self-awareness for any art form to survive.
