After completion; things are done, guard against decline.
The image
Water over fire: water above fire, the pot is cooked. After completion.
Judgment
既濟:亨,小利貞,初吉終亂。
After completion: success in small matters. Perseverance furthers. At the beginning good fortune, at the end disorder. Guard what you have achieved.
