Now circle the right hand clockwise discount dramamine 50mg without a prescription, again keeping the palm toward the body at face level generic dramamine 50 mg online, as the left arm is allowed to pass across the lower abdomen [Photos 29 through 32]. Inhale as the left hand passes the face; exhale as the right hand passes the face. Wave Hands Like Clouds falls into the non-attachment category—if the bottom hand in the movement is stiff and bent, that usually indicates that the stu- dent is holding on to a grievance or other powerful emotion. Effects: This form is good for neurasthenia, gastrointestinal disorders, and indigestion. Putting approximately 70 percent of your body weight on the left leg, bend forward and downward over the leg and scoop up with both hands [Photo 33]. Shift your weight back to your right leg, lift up your left toes, raise your head to look up, and open up your arms, palms up- ward, as you lean back as far as comfortable [Photo 34]. Visualization: You are slowly scooping up water from the seashore, and then looking up in the air. Helps strengthen the kidneys and spleen and develops strength in the legs and waist. After the last looking up movement from Form 11, level your head, drop your hands to chest height, and lower your elbows [Photo 35]. Shift forward 70 percent onto your left leg while pushing forward and upward at chest-level with both hands. Roll back, or shift your weight back onto your right leg while lifting your left toes, and with- draw both hands to your chest. The hands, while shifting forward to push, create a semicircular path: starting from the chest, dropping toward the abdomen as they go forward, and ending once again at chest level, as if you are tracing the bottom of a bowl with your fingertips. Visualization: You are gently rolling back and forth, like waves at the beach. Effects: Good for hepatitis, pulmonary disease, neuralgia, neurasthenia, and insomnia. After the last push from Form 12, the hands are palm forward at chest level, and the weight is 70 percent on the left leg.
