In Section 9 of Attar's Mosibat Nameh, the encounter between Bahlool and Caliph Harun al-Rashid serves as a critique of worldly desire. The narrative relies on a double meaning of the Persian word meyl, representing both a physical milestone and a psychological inclination or desire. Bahlool points out that if the small shadow of a milestone is sufficient to shield the Caliph from the sun, then his vast desire for palaces, gardens, and power is redundant. The poem concludes with a warning comparing the material world to a dragon that swallows both good and bad, emphasizing the Sufi virtue of contentment (qana'at) over greed.
