Align

It is important to maintain optimal postural alignment at all times.
 This means that you must remain loose, alert and flexible - yet sustain peng.
Tai chi form is the main way in which you learn how to move smoothly without losing your good structure.
 Keeping good posture is fairly easy when performing solo work.
 Partner work is another matter entirely.

 All of your hard work may prove irrelevant if you cannot sustain good positioning relative to somebody else.
