We saw nothing more, save for a flame of complexity and brilliance, for even the candle flame, we had witnessed the moth's departure.

This couplet is a masterful depiction of irresistible attraction and singular focus. The poet uses the imagery of a moth and a candle flame. He says that he had seen the moth fly to the flame, but since then, he has only seen one brilliant, complicated flame. It speaks to an intense, obsessive devotion—the kind of love that fixes the gaze on one single, mesmerizing object, ignoring everything else.
