In Chapter 24, Poem 22 of Attar's Mokhtar Nameh, the poet vividly portrays the universe as a relentless and destructive force. The 'wheel of heaven' (چرخ) is depicted as inflicting continuous suffering upon the heart, while the earth is personified as a merciless 'crocodile' (نهنگ) that indiscriminately devours even the most noble and unburdened souls. This imagery emphasizes the inescapable mortality and profound harshness inherent in the material world.
