"Since the documentary Ring of Fire and the books Magus of Java and Nei Kung, many have clamored to learn Mo Pai Nei Kung from a man who calls himself “John Chang.”
This “John Chang” is not the name of the man they seek, but it is a name he uses because he does not want to be bothered by hundreds or thousands of people, who in most cases will not even show the discipline with which to start learning Nei Kung.
This text will explain what you need to do in order to begin Mo Pai Nei Kung. If you accomplish this, then at the end of this text you will be told how to learn Level One of the Mo Pai Nei Kung.
This work itself will discuss the first four levels of Mo Pai Nei Kung, but obviously it does not detail their practice within. Since this book has been released, there has not been even one single person who claimed that they did not receive detailed instruction and follow-up correspondence in Mo Pai Nei Kung."
