In Chapter 26, Poem 26 of Attar's Mokhtar Nameh, the poet explores the motif of the 'unguarded eye' as the origin of the lover's suffering. Looking upon the 'silver-bodied beloved' directly afflicts the lover, causing the heart to turn to blood in its distress. This internal torment then outwardly manifests as tears of blood. The poem illustrates a profound, visceral connection between visual perception of beauty and deep emotional or spiritual torment, a common theme in classical Persian literature.
