Stand on the edge of the circle facing in the counterclockwise direction. Assume the Rolling the Ball Palm posture and then turn the right palm over so it is facing away from you. As you turn it over, bend the elbow so the right palm is level with the forehead.
Another way to find the right-hand palm position is to stand in the Pushing Palm posture and then raise the right hand to the forehead. The left hand remains in its Supporting Palm position. The image is that you are holding a spear between the thumb and forefinger of both hands.
