In Fariduddin Attar's 'Mosibat Nameh' (The Book of Affliction), the story of the dog that discards its bread (kolicheh) to chase the moon serves as an allegory for the futile pursuit of unattainable desires at the cost of what one already possesses. The dog throws away its tangible food to run after the moon, only to end up with neither, leaving it bewildered and empty-handed. Attar uses this narrative to illustrate the spiritual distraction and loss that occurs when one is driven by greed for the unattainable, while emphasizing that true spiritual seeking requires a profound inner pain (dard) that leads to selflessness (fana) rather than worldly greed.
