What is air? Gas is an energy.
Zhuangzi said: "human life, qi is also poly, poly was born, was scattered gas."
All is gas. Initially there is no earth organisms as sunlight, the energy transmitted to the earth continuously, thereby generating a variety of transformed plants, animals, microorganisms. Energy and matter can be transformed into each other, Einstein has proven with his so famous equation: E = mc ^ 2.
The human body is no exception, is composed of gas. People eat food, drink, inhale the air, they are absorbed by the body, it is converted to gas storage in the human body. Gas is converted to a portion of the body's cells, in the form of the substance; another portion of air in the form of energy stored in the human body, this portion is referred to as gas strength. The remaining impurities by metabolism excreted.
Like the electric strength for the operation of various organs and tissues of the human body to power. Meridian as wire cloth in the human body, connecting the various organs, vitality transmitted through the meridians to various organs, organ drive operation.
If some part of the meridian barrier, not by strength from there, then it's back-end organ will be affected. Therefore, "Yellow Emperor" goes: "meridian, it is possible to Daredevil Health, Department diseases, adjusting the actual situation, is not unreasonable."
Why do people have to eat, to drink, to breathe, that is because of the need to absorb energy from the outside, the body added strength to maintain the operation of the human body.
Qigong is that people can control their own body strength to run. After qigong turn out good people, food into his body, energy conversion rate, compared to the ordinary people he has more energy is absorbed and stored. Practicing qigong meditation will be a long time, this time the body into a state of low power consumption, energy consumption is small, but this time, he will still be through food, water, air replenish energy, more energy into less out, more energy is stored as strength. So deep internal strength, his body sufficient strength, far more than ordinary people.
Human resistance to disease, ie immunity is provided by the vitality, strength enough so people do not get sick easily.
Deep internal strength of the person, the greater his power faster. Well understood, gunpowder artillery shells loaded much more quickly fired out speed, of course, the impact of the stronger.
Qigong masters by his acupuncture points (specific point in the meridian), the strength transmitted to the body, which is the outside air. Scientists have done experiments, hair qigong master function, with instrument can pulse signal is detected, infrasound, light waves. You can cure outside air and to be hurt.
Qigong turn out good people, who looks younger. Human aging, because the strength gradually weakened, organ prone to various diseases. So the secret of longevity is to take good caring for her strength.
