In Chapter 4, Poem 35 of Attar's Mokhtar Nameh, the poet explores the mystical concepts of omnipresent divine light and underlying unity. The poem suggests that this divine light permeates both the internal and external realms ('without and within'), yet its true nature remains incomprehensible to human understanding. Attar uses the metaphor of 'a hundred thousand veils' to describe the layers of multiplicity and illusion in the material world. Despite these numerous veils, the ultimate reality that shines through is one of absolute unity (yeganegi), emphasizing the core Sufi principle of Tawhid (the oneness of God) manifesting through all creation.
