The "Book of Changes," also known as the I Ching, is an ancient Chinese text used for divination and philosophical guidance. It consists of 64 hexagrams, which are symbols made up of six lines that can be either broken or unbroken. Each hexagram represents a specific situation or concept, providing insights into the dynamics of change and the natural order of the universe. Divination with the I Ching typically involves casting coins or yarrow sticks to generate a hexagram, which is then interpreted based on the text's commentary. The I Ching emphasizes the importance of adaptability and understanding the flow of life, making it a valuable tool for personal reflection and decision-making.
