This concept explores the core thematic elements in Chapter 16, Poem 7 of Attar's Mokhtar Nameh. The poem instructs the heart to accept relentless, ever-changing sorrows and endure the harsh blows of the 'revolving world' (representing cosmic fate or divine decree). A central Sufi metaphor is employed when the poet describes the head becoming a 'ball upon the path' (گوی ره). In Persian mystical literature, the ball—driven entirely by the polo mallet of the divine will—symbolizes absolute surrender, the loss of individual ego, and complete submission to fate. The act of placing this head on the 'knee of grief' and 'suffering in blood' reflects the ultimate endurance and annihilation of the self required on the spiritual journey.
