Yoga Beyond Belief: Insights to Awaken and Deepen Your Practice by Ganga White Read Free Book Online

yoga, both in the practice of asanas and as its own field of practice, pranayama—the control of breath and energy. Breathing capacity is proportional to the ability to control the breath and to the strength and flexibility of the thoracic area.
    If chest, ribs, and intercostals are stiff, and if we are unable to fully utilize the diaphragm, breathing capacity is limited. Yoga brings flexibility to, gives fine control over, and increases the capacity of the respiratory system. Yogis have shown that health, vitality, longevity, and mental and emotional states are directly related to the breath. These relationships are discussed in more depth in the section on pranayama in Chapter 5 .
The Digestive System and the Eliminative System
    The digestive fire is stoked and toned by exercise. Appetite and the ability to digest foods are greatly increased after exercise. Inverted poses, twists, and forward bends increase the flow of energy to the digestiveand eliminative systems, both by directing energy toward these organs and by releasing compression in the spine to increase nerve flow to the digestive organs. Yoga also brings great attention to diet and nutrition. Eating a clean, healthy diet, free from harmful chemicals and toxins, is part of maintaining the digestive and eliminative systems.
    Pumping bodily fluids through the body with exercise aids the vital internal organs—kidneys, liver, intestines—in their work. The skin is the largest organ of elimination. Exercise and sweating help the skin eliminate toxins and take the load off other organs. Yoga also uses forward bends, twists, abdominal lifts and churning, and internal cleansing practices to stimulate peristalsis, elimination, and “to keep things moving.”
    Health is often judged by the externals of muscle tone, strength, and endurance. But the foundation of health lies in the organs of assimilation and elimination. Yoga practice works toward the health of internal organs not only through the benefits of asana practice but also directly through lifestyle, internal cleansing

The Endocrine System
    The endocrine glands of the hormonal system affect all aspects of growth, development, and function in the body. Hormones are complex and mysterious chemical messengers that transfer information and instructions between cells. They regulate our mood, tissue function, metabolism, and sexual function, pregnancy, and other reproductive processes. Asana practice, especially inversions, backbends, twists, and breath control, are believed to have strong, beneficial effects on keeping the endocrine system in balance.
    After I had been teaching only a few months, one of my first students began having difficulty with her metabolism and energy levelafter a couple weeks of practice. She told me she was on thyroid medication and I recalled that the Shoulderstand was said to help regulate the thyroid. She was doing a five-minute Shoulderstand each day. I suggested that she have her doctor check her thyroid again. Her doctor found that her thyroid had become more active and was able to reduce her medication. This occurred a couple more times over the months until she was able to go off the medication entirely. This example may be exceptional, but many other cases have shown yoga to help bring mood, energy, and metabolism into a more satisfactory balance.
The Nervous System
    The nervous system is a vast network that conducts vital information throughout the body and consists of the brain, spinal cord, nerves, ganglia, and parts of the receptor and effector organs. Yogis pay special attention to the nerves in the spinal cord, which is seen as part of and an extension of the brain. Nerves traveling through the spinal cord control and affect many organs and muscle systems. These nerves exit
