Breathing is controlled by the right brain stem. Stored negative emotions will interfere with breathing. One can also release negative emotions through regulated breathing.
Holding one’s breath is a sign of emotional accumulations. Breathing deeply will release emotions. To train to breathe deeply, start by lying down. Place a few books on the abdomen. When breathing in, breathe into the abdomen so it rises up. When breathing out, relax the abdomen and let the books press it down. Once one has mastered breathing in and out long and deep, then there is no need to use books. Practice while lying down, continue practicing while sitting, standing and walking, breathing deeply all
