In Farid al-Din Attar's Asrar Nameh, the tale of the blindfolded donkey turning a mill serves as a profound allegory for the human condition and spiritual stagnation. The donkey walks tirelessly from dawn to dusk, believing it has traveled a vast distance, only to realize upon having its blindfold removed that it has not moved beyond its starting point. Attar uses this narrative to illustrate how humans, bound by earthly habits, customs, and the ego, toil endlessly in the material world without making true spiritual progress. The poem concludes that ultimate liberation and peace are found not in this cyclical worldly existence, but in spiritual annihilation (Fana).
