The idea of increase is expressed in the fact that the strong lowest line of the upper trigram has sunk down and taken its place under the lower trigram. This conception also expresses the fundamental idea on which the Book of Changes is based. To rule truly is to serve. A sacrifice of the higher element that produces an increase of the lower is called an out-and-out increase: it indicates the spirit that alone has power to help the world.
