If a mirror is not seen by anyone, who can tell the story of the image and its reflection? This implies that without an observer, their tale remains untold.

This couplet beautifully suggests that if you never bother to look into a mirror, how will you ever know about your own image and its reflection? It's a profound thought about self-awareness. It means that if we don't take the time to introspect and understand ourselves, who will explain our true nature to us? The mirror here isn't just a physical object, but a symbol of self-reflection and inner examination. Without this internal gaze, the story of who we truly are, our strengths, our weaknesses, our inner self, and how it projects into the world, remains untold and unknown. It encourages us to look within to discover our own truth.
