When the wind blows over the earth it goes far and wide, and the grass must bend to its power. These two occurrences find confirmation in the hexagram. The two images are used to symbolize a practice of the kings of old; in making regular journeys the ruler could, in the first place, survey his realm and make certain that none of the existing usages of the people escaped notice; in the second, he could exert influence through which such customs as were unsuitable could be changed. All of this points to the power possessed by a superior personality. On the one hand, such a man will have a view of the real sentiments of the great mass of humanity and therefore cannot be deceived; on the other, he will impress the people so profoundly, by his mere existence and by the impact of his personality, that they will be swayed by him as the grass by the wind.
