This change differs from the previous palms in that the arms do not complete their change until you take the Sweeping Step.
Stand on the edge of the circle facing in the counterclockwise direction. From Holding the Spear Posture, lower the right hand down the front of the body with the palm facing away, while the left hand rises from its extended position with the palm facing to the body.
You can over stretch this posture by raising the left shoulder and straightening the left elbow. If you want to maintain the Wuji Posture alignments, you will not straighten the left elbow. I prefer the latter posture, but either is acceptable.
