How does someone with no or little knowledge of internal skills really know if someone directly is teaching them really does understand or has good internal skills? It is really easy to fool those novices seeking intensely internal skills to improve their skills- there is some kind of psychological thing that happens in that, that people will drop critical thinking and judgement accepting whole heartily anything taught to them at the real deal. They do this because they hear a good line and convinced by it, and thus that is what they want to hear. They really want internal skills so badly, they accept what they hears as the facts easily convince who they hear it from is an expert in internal skills because they talk a good talk. There is no one else or background knowledge/experience to make comparison to determine what is real and what isn't.
