What’s one of the overarching themes I have explained throughout these principles?  Connectedness!  Now on surface level of this statement its pretty straight forward.  Your body–every fiber, muscle and joint– must be connected to accept and deliver the maximum amount energy.  When one part moves it all moves in some fashion (even at a very microscopic level) and when one part is still it all must be still.  External energy is maximized with this principle.  You can become truly fluid and move like the wind when all parts are truly connected.

But wait there is more!  Internal martial arts deals has an inside to deal with.  You must learn to connect all these parts together as well to generate and build energy then refine spirit.  Without these concepts your internal martial art is merely an external shell of a form.

Without unifying everything your results will be modest at best.  Some people learn to move well, and are truly beautiful and can generate decent amounts of power but they do not work internally so they can never break that glass ceiling of  power generation.  Others work only on internal aspects but let they body go to hell so they can barely move or are sluggish and slow.  This power generated is still modest and in most aspects worse than the external people.  Yin and Yang must balance.  It’s concept, like explained earlier, is easy to say but very hard to actually implement.  Your body, internally and externally, must be connected to generate the true potential of internal martial arts.
