The I Ching, also known as the Yi Jing, or (in English) Book of Changes, is an oracle; a divination device that forms a pattern reflecting the forces at work in the Universe at a particular point in time. The I Ching has been used for more than 5000 years as an aid to making decisions, predicting the future, etc. So, if nothing else, it is a long-standing and popular source of wisdom and inspiration. The I Ching is a collection of practical wisdom, pertaining to every conceivable situation. It originates in ancient China and is the oldest Chinese classical text. "I Ching" means "Classic of Changes" or "Book of Changes." (While mostly the spelling "I Ching" is used, "Yijing" is in fact the official modern spelling.) There are 64 different main kinds of situations in the I Ching. Each one is indicated by a hexagram, which is a symbol made up by 6 lines, each of which can be broken or unbroken. To obtain advice from the I Ching about one's current situation, one can consult it as an oracle. To decide which hexagram is related to the situation at hand, a "random" hexagram is obtained by throwing coins (or yarrow sticks, that traditionally were used). The "random" hexagram is supposed to not be random at all, but to coincide with the situation.
