Whether my inner passion was born or was pre-ordained, if I had not restrained it, this entire city would have burned.

This profound couplet speaks to the immense power of unchecked emotion. The poet suggests that his inner passion, whether inherent or merely concealed, is a raging fire. He warns that if he were to release this passion—if he did not restrain it—the entire world, the 'city,' would burn down. It is a powerful metaphor for the destructive nature of intense, uncontrolled desire or love.
