In Chapter 18, Poem 26 of Attar's Mokhtar Nameh, the poet contrasts physical wandering with spiritual exploration. He asserts that traversing the external world, even surpassing the movement of the celestial sphere, is ultimately futile. True spiritual progress requires an inward journey, metaphorically described as traveling 'around one's own head and feet'. This highlights the primacy of self-discovery and inner transformation over outward seeking.
