The name joins
既 'already' and
济 'to cross a river': the crossing is done. The hexagram sets water above fire and has every line in its proper place, a picture of perfect order, yet its judgment warns
初吉终乱 'good at the start, disorder at the end'. Its image commentary says
君子以思患而豫防之 'the gentleman thinks of trouble and guards against it beforehand', the root of
防患于未然.
