The I-Ching was said to have been created by King Wen about the sixth century BC. He was held prisoner and used his creation (the I-Ching) to entertain his enemies, who were so impressed with his prophecies,he was eventually released. The way it works is fairly simple; it is made up of 64 hexagrams, which are made by combining two trigrams(which were outlined on the previous page). By "tossing the coins", a result of straight and/or broken lines is compiled, and a prophecy is laid out. It is called the Book of Changes because it relies on the belief that our lives are ever changing, nothing remains the same. It gives two pieces of information; the first being the present situation and the second, the situation to come. The eight trigrams surround the yin yang symbol to complete the Bagua, used in feng shui.
