Begin with the un-polarized pose.  Raise the arms forward at an angle to eye level, palms facing downward.  Then, while continuing to raise the hands a little higher than the head, turn the palms gradually to face each other.  Palms and fingers should slant upward.  Imagine that you are touching the surface of a big ball.  Continue the movement by turning the palms downward.  Then lower the hands to the level of Dantian, fingers pointing toward each other.
 
Breathe in while raising your arms and breathe out while lowering them.  Remember to relax the shoulders and drop the elbows while raising the arms.  You can feel the chi filling the Dantian while you are lowering the hands in front of your body.  Repeat the movement many times.
