Move as quietly as a cat...
Put forth strength so mild that it is as if you are reeling silk from a coccoon ...
Don't let your movements become aimless and lifeless; this is a common mistake, your movements should be purposeful as well as relaxed...
Your mind should be tranquil and calm with your focus commanding your body...
If you find your thoughts drifting as you practice, just bring them back to the movements and you will find a lovely stillness
(this may take a few weeks)...
Everything should move in unison...
Straight but not straight, bent but not bent..
