In Attar's 'Tale of Sultan Mahmud and the Duval-Player' from the Elahi Nameh, the encounter between the mighty Sultan Mahmud and a lowly street gambler (duval-player) serves to illustrate the Sufi concept of 'pak-bazi' (pure playing, or risking and losing everything for the sake of the divine). When Mahmud condescendingly addresses the gambler, the man responds that the trappings of worldly power and kingship are fundamentally incompatible with the spiritual path. He advises the Sultan to become entirely detached from worldly attachments, emphasizing that spiritual perfection is only achieved through 'pak-bazi'—giving up one's heart and soul entirely and holding nothing back in the pursuit of divine truth. This tale contrasts the illusion of worldly power with the absolute surrender required for true spiritual attainment.
