否 → 夬

Commentary

Heaven and earth stand sealed as birds stumble and limp in flight, yet two by two they harmonize with each other. Their four limbs are uninjured — simply go forward without hesitation. From Standstill to Breakthrough, Pi's blockage meets the lake rising above heaven — the decisive moment when accumulated waters burst through. Guai demands resolute action: the one remaining yin line must be removed for the five yang lines to prevail. The stumbling birds that nonetheless fly in pairs capture Guai's lesson: imperfection is no excuse for inaction. The limbs are sound; the stumble is momentary. Breakthrough requires not flawless grace but the willingness to launch despite awkwardness, trusting that the pair will steady each other in flight.
