In Chapter 12, Poem 1 of his Mokhtar Nameh, Attar of Nishapur explores the fundamental limitations of human knowledge regarding the ultimate "secrets of truth" (اسرار حقیقت). The poem suggests that because the divine mystery is entirely beyond human comprehension, the most appropriate human response is brevity (کوتاهی) and silence. Attar contrasts God's absolute omniscience—perceiving all things from the celestial heights to the earthly depths ("from the moon to the fish")—with humanity's profound ignorance, noting that mortals cannot attain even a "hair's breadth" of true awareness.
