The waters on the surface of the earth flow together wherever they can, as for example in the ocean, where all the rivers come together. Symbolically this connotes holding together and the laws that regulate it. The same idea is suggested by the fact that all the lines of the hexagram except the fifth, the place of the ruler, are yielding. The yielding lines hold together because they are influenced by a man of strong will in the leading position, a man who is their center of union. Moreover, this strong and guiding personality in turn holds together with the others, finding in them the complement of his own nature.
