Let the ball begin to shrink purchase 50 mg nizagara, such that your palms begin to approach each other. Now let the hands glide gracefully past each other without touching, the left hand continuing downward to your left side, the right hand stretching upward on the right side. At the completion of this move, your torso should be facing forward, your left arm down at your left side (slightly away from the chair) with the palm facing back- wards and the fingers pointing down. Your right hand should be stretching upward at your right side, fingers pointing upward and palm facing forward. Now reverse the hand motions, lifting the left hand up and allowing the right hand to drop. The left will rise in front of your body, palm up, while the right de- scends palm down. The hands will begin coming together as if holding the ball again, this time with the right hand on top. Continue the motion, letting the ball shrink and allowing the hands to pass by each other as they move to their new positions—the left hand reaching and pointing to the sky, palm forward, and the right hand reaching and pointing to the earth, palm backward. Now lift and extend the right hand forward and upward at a 45-degree angle, pushing with the palm and pointing the fingers upward. As you draw your right hand back into the side of your body, simultaneously turning it palm up, lift and extend the left hand in the same fashion as you did the right: fingers pointing up and pushing with the palm at a 45- degree angle.
