3rd Harmony: Combine your Intent and your Qi yi he yu qi意合于气

You have worked hard and you understand the movements internally and externally.  You have started to develop Nèiwài wéi yītǐ (内外为一体)!  Now the hard work comes in.  That intention must drive your internal energy throughout the form.  You must combine the inside with the outside and make it one.  Without your Qi there will be no true strength.  Now you may have some physical strength applied but that is not the intent with internal martial arts.  Physical strength can be strong but is considered a dead or stiff energy.  You need to develop that lively power; a person needs to relax their physical body, align it properly, and use internal principles to create Li (力).  Physical strength can decline quickly in older age (modern medicine and greater understanding of physical training has helped extend this to some extent though) but internal strength can stay with a person to the end of your days if properly maintained and practiced.  To be 90 years old but move like your 30 and hit like your 20 is possible.  It takes true dedication and understanding but yet still attainable.  It starts with this harmony.

Now a person must truly start to practice and dedicate themselves.  You have to make your energy abundant through diligent practice.  This can be accomplished in a myriad of ways, either through the form, zhan zhuang, silent meditation, other internal arts etc.  However the more you practice the one form (Liu He Ba Fa in this instance) and engrain the energy with it the better it will be.  Qi must be driven throughout your body; your 4 extremities filled evenly.  Your lower dan tian will become full and hard like a rock.  Once you have put the energy into thebank (so to speak) you can then withdrawal it, focus it throughout the form, and demonstrate true internal strength.  Once your internal energy combines with your external movements you will have true Fa li and your form will look relaxed yet very powerful.
