Taking a unique look at the novel Xi You Ji(Journey to the West), this book is a pioneer book in the relevant literature. Xi You Ji is not a fictionalized novel, as the majority people thinks, about pilgrimage of the Chinese Buddhist monk Xuan Zang who journeyed to India to seek for Buddhist Scriptures. Instead, deep inside it is all about Internal Alchemy. It is in fact a book that describes covertly different steps to cultivate inside the human body 'golden elixir', an immortal spiritual body beyond the realistic world. The process also relates a lot with the context of I Ching. This book discusses what the characters in the book represents and which step of Internal Alchemy each story corresponds to. None of these topics have been so thoroughly discussed since Xi You Ji came into existence, needless to say in precise and clear modern language. Anyone who likes The Secret of the Golden Flower by Carl Jung and able to read Chinese is likely to enjoy this book.
