This poem from Attar's Mokhtar Nameh explores the theme of universal mortality using the metaphor of the "millstone of the inverted sky" (the revolving celestial sphere). It emphasizes that the heavens relentlessly grind down all beings, rendering worldly pursuits and illusions futile. The poet highlights the inescapable reality of decay, posing a rhetorical question to point out that no one who comes into existence can ever evade this cosmic force of destruction.
