Sit up straight on the edge of a chair with the backs of your hands resting on your thighs and become aware of your lungs.
1 - Take a deep breath and, letting your eyes follow, raise your arms up in front of you. When the hands are at eye level, begin to rotate the palms and bring them up above the head. Keep the elbows rounded. You should feel a stretch that extends from the heels of the palms, along the forearms, over the elbows, along the upper arms and into the shoulders. The lungs and chest will feel open and breathing will be easier.
2 - Close the jaws so that the teeth meet gently, and part the lips slightly. Draw the corners of the mouth back, exhale, and allow your breath to escape through the spaces between the teeth, making the sound "SSSSSS", sub-vocally, slowly, and evenly in one breath.
3 - As you do this, picture and feel the sac covering the lungs being compressed, ejecting the excess heat, sick energy, sadness, sorrow, and grief.
4 - When you have exhaled completely (without straining), rotate the palms down, close the eyes, and breathe in to the lungs to strengthen them. If you are colour oriented, you can imagine a pure white light and quality of righteousness entering into your whole lung. Float the arms down by gently lowering the shoulders. Slowly lower them to your lap so that they rest there, palms up. Feel the energy exchange in the hands and palms.
5 - Close the eyes, breathe normally, smile down to the lungs, be aware of the lungs, and imagine that you are still making the sound. Pay attention to any sensations you may feel. Try to feel the exchange of cool, fresh energy replacing hot waste energy.
6 - When your breathing calms down, repeat the sequence 3 to 6 times.
