The Yi Jing (or I Ching as it is more commonly written) is the Classic of Changes, a book that was written more than 3000 years ago. (According to one legend, it is even older, with emperor Fu Xi discovering the signs of the I Ching marked on the back of a tortoise around 2800 BCE.) It is one of the five classics of ancient China.
Hexagram 25 from the Yi Jing, which can be translated as 'innocence'
The I Ching is a book of divination, used to predict and plan for the future. The reader makes an enquiry about their future — for example, “What will happen if it quit my job?”, “Should I get married?”. Then they select one of the 64 chapters of the I Ching and read it to find the answer to their query.
In ancient times, the reader used a complicated system of dividing a bundle of yarrow stalks to select the relevant chapter. Nowadays people throw three coins six times. For each throw they draw a line, which is either solid or broken in two, depending on the sequence of heads and tails. The lines from six throws create a hexagram. Each hexagram relates to one of the 64 chapters of the I Ching. The person making the enquiry reads the chapter, and then tries to work out how that relates to their own question. It needs a lot of interpretation!
The I Ching has been translated into many languages, and even though it is at least 5000 years old, people still use it today to help them make decisions about their future.
