In Chapter 10, Poem 3 of Attar's Mokhtar Nameh, the poet addresses the human soul as a "wondrous bird" bound by a primordial covenant since the Day of Alast. The poem revolves around the motif of the "World-Revealing Cup" (Jam-e Jahan-nama)—a legendary artifact in Persian mythology believed to reflect the entire universe. Attar internalizes this myth by asserting that the true cup is not an external object but is hidden "in a chest within your breast." This illustrates the core Sufi teaching that the human heart is a microcosm containing the macrocosm of the divine reality, emphasizing that the ultimate search for universal truth requires an inward journey rather than outward exploration.
