《易经》, also known as the I Ching or Book of Changes, is an ancient Chinese text that serves as a divination system and philosophical guide. It consists of 64 hexagrams, each made up of six lines that can be either broken or unbroken, representing yin and yang. The text explores the principles of change and balance in life, offering insights into human behavior and the natural world. The I Ching has influenced various aspects of Chinese culture, including Confucianism, Taoism, and traditional Chinese medicine. It is often used for decision-making and self-reflection, with practitioners interpreting the hexagrams to gain wisdom and guidance in their lives.
