In Chapter 14, Poem 13 of Attar's Mokhtar Nameh, the poet admonishes the heart for bearing the grief and anguish of the material world. He employs a striking metaphor, likening the worldly domain to a furnace or ash-pit (گلخن) inhabited by pigs and dogs, which symbolize base, animalistic desires and the carnal ego (نفس). By questioning why one would consume a morsel from such a vile place when even fire would be preferable, Attar emphasizes the profound worthlessness of material attachments and urges the spiritual seeker to abandon worldly sorrow.
