M1:3564 — گفت یک اصبع چو بر چشمی نهی / بیند از خورشید عالم را تهی

This beyt comes in the context of a discussion about how the human perception, despite its limitations, is meant to recognize truth. The preceding lines question what value humans have if they cannot discern truth, comparing them to a mirror that cannot reflect the beautiful. Rumi then introduces the idea that even a small, seemingly insignificant act can obscure a grand reality. The analogy of placing a finger over one's eye is profoundly simple yet powerful. The sun, a symbol of universal light, truth, and often God's presence, is always there, but a tiny obstruction—one's own finger—makes the entire world appear dark and empty of its light. This points to the idea that our ego, our self-centeredness, or even a minor attachment can act as that 'finger,' preventing us from perceiving the omnipresent divine reality.
