It is essential to breathe in as well as out through the nose. the stomach should rise gently like a balloon being blown up, and the muscle structure should remain supple: should you wish to control the movement you may place your hand on your stomach near the navel, at the same time resting the elbow on the floor. In this way it is easy to follow the expanding movement of the stomach. While this is going on, place the other hand against one side so that you can ensure that the ribs remain completely still, and so realize that the abdominal and thoracic breathing are completely separate. Should your ribs still move while the stomach is rising, they should be immobilized by girding the thorax with a belt placed near the lower part of the sternum, in the pit of the stomach. Fasten the belt when the lungs are empty, to the required girth. While you breathe in the breathing and your diaphragm will be forced to flatten and your stomach to expand. While you are breathing in, you should be conscious of what is going on in the warm depths of the thorax; you will soon find you are conscious of the movements of the diaphragm, and you will be able to separate the two phases and dispense with the belt.
