In Chapter 4, Poem 11 of Attar's Mokhtar Nameh, the poet explores the theme of arduous spiritual seeking culminating in the realization of divine immanence. The 'forty years' with the 'eye of madness' symbolizes a prolonged period of intense spiritual discipline, trial, and maturation. Upon surpassing this stage, the seeker achieves a visionary state, witnessing the 'sun' (representing divine light or ultimate reality) radiating from the 'window of every speck of dust.' This reflects the core Sufi concept of witnessing the macrocosm within the microcosm, where every single atom of the universe serves as a direct window to the Divine Presence.
