The I Ching (Book of Change) is considered the oldest of the Chinese classics, and has throughout Chinese history commanded unsurpassed prestige and popularity. Containing several layers of text and given numerous levels of interpretation, the I Ching has been venerated for more than three thousand years as an oracle of fortune, a guide to success, and a source of wisdom. The underlying theme of the text is change, and how this fundamental force influences all aspects of life—from business and politics to personal relationships. This translation of the I Ching draws on ancient Confucian commentary, which emphasizes applying practical wisdom in everyday affairs.
