In Poem 47 of Chapter 4 in Attar's Mokhtar Nameh, the poet continues to emphasize the profound epistemological limits of human beings when faced with the ultimate divine mystery. Echoing the recurring refrain of the previous poem ('neither you... nor I'), Attar reiterates that this existential riddle cannot be solved by any human intellect. Confronted with the absolute inability to comprehend even a 'single particle' of the truth, he concludes that intellectual pride is futile. Because there is no opportunity for the ego to 'raise its head' in mastery of this secret, the only appropriate human response is to 'swallow grief'—embracing spiritual humility and the sorrow of our fundamental limitation.
