The ''I Ching'' or ''Yijing'' ( ), usually translated ''Book of Changes'' or ''Classic of Changes'', is an ancient Chinese divination text that is among the oldest of the Chinese classics. The ''I Ching'' was originally a divination manual in the Western Zhou period (1000–750 BCE). Over the course of the Warring States and early imperial periods (500–200 BCE), it transformed into a cosmological text with a series of philosophical commentaries known as the Ten Wings. After becoming part of the Chinese Five Classics in the 2nd century BCE, the ''I Ching'' was the basis for divination practice for centuries across the Far East and was the subject of scholarly commentary. Between the 18th and 20th centuries, it took on an influential role in Western understanding of East Asian philosophical thought.

As a divination text, the ''I Ching'' is used for a Chinese form of cleromancy known as ''I Ching'' divination in which bundles of yarrow stalks are manipulated to produce sets of six apparently random numbers ranging from 6 to 9. Each of the 64 possible sets corresponds to a hexagram, which can be looked up in the ''I Ching''. The hexagrams are arranged in an order known as the King Wen sequence. The interpretation of the readings found in the ''I Ching'' has been discussed and debated over the centuries. Many commentators have used the book symbolically, often to provide guidance for moral decision-making, as informed by Confucianism, Taoism and Buddhism. The hexagrams themselves have often acquired cosmological significance and been paralleled with many other traditional names for the processes of change such as yin and yang and Wuxing.
