The I Ching or "Book of Changes" is the oldest of the Chinese classic texts. It describes an ancient system of cosmology and philosophy which is at the heart of Chinese cultural beliefs. The philosophy centers on the ideas of the dynamic balance of opposites, the evolution of events as a process, and acceptance of the inevitability of change. In Western cultures, the I Ching is regarded by some as simply a system of divination; many believe it expresses the wisdom and philosophy of ancient China.
