It is related to the chakra of the throat and heart. The abdominal center is related to the base, sacral and solar plexus chakras and is concerned with the practical aspects of life and physical activity. Ideally, energy should be divided equally among the three centers. Factors, such as activity, education, diet, culture, etc, prevents this from happening so. In shiatsu, more importance is attached to the abdominal center, known as the hara.
Many exercises are available to help hara.
We recommend that you do the deep breathing exercises described under the yoga breathing exercises . Once this technique is mastered, use a visualization to improve the effectiveness. While inhaling, imagine that ki is being inhaled down into the hara. Inhale slowly via the nose and imagine the ki descending. The breath should be held for about four seconds and concentration should be centered on the ki.
