The I-Ching ends not with completion but with a pair: Hex 63 (After Completion) and Hex 64 (Before Completion). This is the most Daoist gesture in the entire sequence. Hex 63 is water over fire — every line in its 'correct' position, maximum order achieved. Hex 64 is fire over water — every line 'incorrectly' placed, maximum potential restored. Daoism would say: of course the book ends here. Completion and incompletion are not sequential stages — they are simultaneous aspects of every moment. The Dao De Jing (Chapter 45): 'Great perfection seems imperfect, yet its use is inexhaustible. Great fullness seems empty, yet its use is endless.' The I-Ching's final word is the same as Laozi's: there is no final word. The sequence that ends at 64 flows back to 1. The serpent eats its tail. The work continues.
