Also finished reading this, which I bought from Joscephine about a week ago. It is a treasure trove of simple but ancient divination systems. I particularly like the section on joss stick divination. One must observe the joss sticks when they are lit halfway. The heights of the sticks mean certain things and prescribe certain actions.

I can see why many people might be turned off by the book, though. It is written in English as a third language and its use of idioms can be misleading. It should at the very least be read keeping in one's mind that it is a translation, even if it is not.
