In Chapter 24, Poem 34 of Attar's Mokhtar Nameh, the poet explores the transience of life by depicting the earth as the worn-down remains of past generations. The metaphor of the heavens as a millstone (آسیای چرخ) illustrates the inescapable and destructive power of cosmic time, which grinds all physical bodies into dust. Attar advises humility, reminding the reader that the dust settling upon their head was once the cherished head of another, emphasizing the cyclical nature of mortality and the physical world.
