In Chapter 27, Poem 14 of Attar's Mokhtar Nameh, the poet reflects on the ultimate emptiness of worldly pursuits. He describes a heart that is bewildered and captivated by the world but ultimately gains no true profit from it. Despite nurturing vast and vain ambitions, the end result is complete nothingness, emphasizing that worldly attachments yield no lasting substance, yielding not even a 'wisp of smoke.'
