In Chapter 11, Poem 5 of Attar's Mokhtar Nameh, the poet contrasts the spiritual and physical realms and highlights the struggle of the physical body. He describes bodies as constantly striking against obstacles, searching for a way out. The poem concludes with the profound realization that "Every atom is a door, but it is nailed shut." This paradox suggests that although potential pathways or signs of the divine exist everywhere in the universe, they remain inaccessible or closed off to those relying solely on their physical senses or unawakened faculties.
