The I Ching, also known as the Book of Changes, is an ancient Chinese divination text that serves as a foundational work in Chinese philosophy and culture. It provides guidance through a system of 64 hexagrams, each composed of six broken or unbroken lines, representing different states of change and patterns in life. The I Ching is significant not only for its role in divination but also for its philosophical insights into the nature of existence and the concept of balance and harmony.
