Tu Na - Inhale new, expel old

Find a quiet, comfortable place to sit or stand with your back upright. If you are sitting, plant your feet firmly on the ground.

Take a slow, deep breath in through your nose, directing the air deep into the diaphragm and using it to stimulate the lower abdomen. You will notice that your belly expands as you inhale, rather than your chest.

Hold your breath for a moment, then exhale slowly and completely, imagining any tension or negative energy leaving your body.

Exhale slowly through your mouth, releasing the breath and any tension or negative energy from your body. If needed, blow hard to remove any toxins.

You can repeat this cycle of breathing for several minutes, gradually extending the length of your inhales and exhales as you become more comfortable with the technique.
