I Ching

The I Ching , also known as Classic of Changes or Book of Changes, is an ancient Chinese divination text and the oldest of the Chinese classics. Possessing a history of more than two and a half millennia of commentary and interpretation, the I Ching is an influential text read throughout the world, providing inspiration to the worlds of religion, psychoanalysis, business, literature, and art. Originally a divination manual in the Western Zhou period (1000-750 BC), over the course of the Warring States period and early imperial period (500-200 BC) it was transformed into a cosmological text with a series of philosophical commentaries known as the "Ten Wings." After becoming part of the Five Classics in the 2nd century BC, the I Ching was the subject of scholarly commentary and the basis for divination practice for centuries across the Far East, and eventually took on an influential role in Western understanding of Eastern thought.
