In Chapter 40, Poem 10 of Attar's Mokhtar Nameh, the poet employs a striking metaphor to express the extreme intimacy between the lover and the beloved. By describing the beloved as the lover's own eye, the poem highlights a spiritual paradox: just as an eye cannot perceive itself, the lover cannot see the beloved because the beloved has become the very organ of their perception. This illustrates the mystical concept of absolute unity, where the duality of the observer and the observed is entirely dissolved.
