"The Book of Changes was a collection of linear signs to be used as oracles. In antiquity, oracles were everywhere in use; the oldest among them confined themselves to the answers yes and no. This type of oracular pronouncement is likewise the basis of the Book of Changes. "Yes" was indicated by a simple unbroken line (___), and "No" by a broken line (_ _). To each of these combinations a third line was then added. In this way the eight trigrams came into being. These eight trigrams were conceived as images of all that happens in heaven and on earth. At the same time, they were held to be in a state of continual transition, one changing into another, just as transition from one phenomenon to another is continually taking place in the physical world. Here we have the fundamental concept of the Book of Changes. The eight trigrams are symbols standing for changing transitional states; they are images that are constantly undergoing change. Attention centers not on things in their state of being -- as is chiefly the case in the Occident -- but upon their movements in change. The eight trigrams therefore are not representations of things as such but of their tendencies in movement. "
