I began my search in internal arts in the late 50's. The problem I see today is you are deluged with mis-information. It sells books but doesn't produce much. You need to understand, first of all, that true internal art has very little to do with modern MA. If you look at the history offered for most internal arts, they usually refer to a Taoist or a Buddhist or a Monk who originally taught their schools founder. In most systems of Tibet or India you'll find discussion of internal channels in the body. (Nadis in India) Cleaning out these channels was the aim of internal art. Once cleaned out, their meditation was much more clear. If someone learned some physical moves, it is highly unlikely they also learned all of the inner exercises. Sometimes the moves sort of look like MA moves but actually aren't. However if you developed the idea that this inner energy could be developed and you could use it for the purposes of your ego, you'd actually be working in the opposite direction, and dirtying the channels instead of cleaning them out. In MA applications there is one law. "I, Chi, Lik" (In cantonese) and "I, chi, Li (in Mandarin). Which is to say what or where you intend, the energy wil appear and do the work intended. That won't help you much without correct moves to correlate to it.
