A journey of a thousand miles may indeed start with one step. But are you really going anywhere?
This is an important question.
Although your physical position may alter relative to external objects, are 'you' actually going anywhere at all?
Do you understand?

Tap your chest. You are here. Now walk across the room. Tap your chest again. You are still here.
Your body may have moved across the room, but 'you' haven't gone anywhere at all.

If you realise that your body occupies the same space at all times, then you see the form and your relationship with an opponent quite differently.
This is what 'central equilibrium' is really about.

The form is merely exploring variations of the three dimensions. You turn the waist, shift the weight, move the hands, the legs, the eyes. 
But you essentially remain exactly where you are.
