Unfortunately, as far as I am aware, this system has not been introduced in the English language before, despite there are many English I Ching books in the market. To demonstrate this interesting system, let us look at an example. To use I Ching Divination method , we have to cast 3 metal coins 6 times to get 6 lines for constructing a Hexagram. One head means a yang line. Two heads means a yin line.
All heads means a yang line changing into yin.
All tails means a yin line changing into yang. After this casting process, a Hexagram will appear with Yin and Yang lines as well as active changing lines showing areas of action. The purpose of this I Ching Divination exercise is to find hints to see who is likely to be the killer. How to interpret this Hexagram to get the answer. The first step is to establish our focus.
