Naguib Mahfouz, in his book "The Mirage," presents a profound idea about perception and understanding. He suggests that the heart possesses its own vision, a deeper awareness that can overshadow the physical sight provided by our eyes. This metaphor implies that emotional insight can either clarify or obscure reality, depending on how intensely one feels or focuses on a particular truth.

This statement emphasizes that when one becomes deeply engrossed in their feelings or desires, they may fail to see the world around them clearly, leading to a blindness to other perspectives or truths. It serves as a reminder of the complexities of human experience, where emotional perceptions often shape our understanding of reality.
