In Chapter 20, Poem 15 of Mokhtar Nameh, Attar of Nishapur explores the futility of human ambition driven by the ego. He uses the metaphor of 'measuring the wind' to highlight the absurdity of a human being—who is fundamentally nothing more than the 'dust of the path'—engaging in vain and impossible pursuits. The poem warns that any attempt to inflate one's ego or add to one's sense of self ('Whatever you add from yourself') ultimately leads to spiritual diminishment and entanglement in self-created impossibilities. True spiritual progress requires abandoning such vain ambitions and recognizing one's inherent insignificance.
