After Completion
Every Line in Place
Legge's 1882 Tuan explains After Completion's final disorder through a cessation of effort; it does not say that perfection itself automatically causes collapse.
James Legge, The Yî King (Sacred Books of the East XVI, Clarendon Press, 1882), Text, LXIII, pp. 205–207; Appendix I, LXIII, p. 265; Appendix II, LXIII, pp. 345–346.
Hexagram 63 of the Yijing: Water above Fire, alternating firm and broken lines.
More context
Ji Ji places Water above Fire. Its alternating firm and broken lines occupy the conventionally correct odd and even positions. The oracle promises progress in small matters, good fortune at first and disorder at the end. The Tuan commentary connects the final disorder with a cessation of effort. The Great Image responds by anticipating danger and guarding against it. In Legge's 1882 note, the task is consolidating a government after relief of disorder, rather than assuming that nothing remains to be improved.
Light
The Great Image makes anticipation and preparation part of an ordered condition; success can be followed by deliberate consolidation.
Shadow
The oracle warns of disorder at the end, and its Tuan commentary identifies a cessation of effort.
