Qi Gong is an ancient Chinese energy (Chi) practice. Qi means energy, Gong means work. It is based on the concept of Qi energy which flows through the body. It is used for both medical and health purposes and to improve the effectiveness of martial arts practise. Much Qi Gong is now a mixture between Daoist & Buddhist energy cultivation practises. Qigong is a self-healing art that combines movement and meditation. Visualizations can be employed to enhance the mind/body connection and assist healing. The history of Chinese Qigong can be roughly divided into four periods.
Little is known about the first period, which is considered to have started when the Yi Jing - Book of Changes was introduced sometime before 1122 B.C., and to have extended until the Han dynasty (206 B.C.) when Buddhism and its meditation methods were imported from India. This infusion brought Qigong practice and meditation into the second period, the religious Qigong era.
This period lasted until the Liang dynasty (502-557 A.D.), when it was discovered that Qigong could be used for martial purposes. This was the beginning of the third period, that of martial Qigong. Many different martial Qigong styles were created based on the theories and principles of Buddhist and Daoist Qigong. This period lasted until the overthrow of the Qing dynasty in 1911; from that point Chinese Qigong training was mixed with Qigong practices from India, Japan, and many other countries.
The Yi Jing - Book of Changes (1122 B.C.) was probably the first Chinese book related to Qi. It introduced the concept of the three natural energies or powers (San Cai): Tian (Heaven), Di (Earth), and Ren (Man). Studying the relationship of these three natural powers was the first step in the development of Qigong. During the Zhou dynasty (1122-934 B.C.), Lao Zi mentioned certain breathing techniques in his classic "Dao De Jing" (or Tao Te Ching) (Classic on the Virtue of the Dao). He stressed that the way to obtain health was to "concentrate on Qi and achieve softness". About 300 B.C. the Daoist philosopher Zhuang Zi described the relationship between health and the breath in his book Nan Hua Jing. "The men of old breathed clear down to their heels." The Daoist Jun Qian used the movements of animals to create the Wu Qin Xi (Five Animal Sports), which taught people how to increase their Qi circulation through specific movements.
In the Shaolin Temple Bodhidharma developed, after nine years of seclusion, two classics: Yi Jin Jing - Muscle/Tendon Changing Classic and Xi Sui Jing - Marrow/Brain Washing Classic. The Muscle/Tendon Changing Classic taught the priests how to gain health and change their physical bodies from weak to strong. The Marrow/Brain Washing Classic taught the priests how to use Qi to clean the bone marrow and strengthen the blood and immune system, as well as how to energize the brain and attain enlightenment. After the priests practiced the Muscle/Tendon Changing exercises, they found that not only did they improve their health, but they also greatly increased their strength. When this training was integrated into the martial arts forms, it increased the effectiveness of their techniques. It soon became an important part of their training.
Outside of the monastery, the development of Qigong continued during the Sui and Tang dynasties (581-907 A.D.).
Chao Yuan-Fang compiled the Zhu Bing Yuan Hou Lun (Thesis on the Origins and Symptoms of Various Diseases), which is a veritable encyclopedia of Qigong methods listing 260 different ways of increasing the Qi flow.
The Qian Jin Fang (Thousand Gold Prescriptions) by Sun Si-Mao described the method of leading Qi, and also described the use of the Six Sounds. During the Song, Jin, and Yuan dynasties (960-1368 A.D.), Yang Shen Jue (Life Nourishing Secrets) by Zhang An-Dao discussed several Qigong practices. Ru Men Shi Shi (The Confucian Point of View) by Zhang Zi-He describes the use of Qigong to cure external injuries such as cuts and sprains. "Lan Shi Mi Cang" (Secret Library of the Orchid Room) by Li Guo describes using Qigong and herbal remedies for internal disorders. "Ge Zhi Yu Lun" (A Further Thesis of Complete Study) by Zhu Dan-Xi provided a theoretical explanation for the use of Qigong in curing disease.
During the Song dynasty (960-1279 A.D.), Chang San-Feng is reputed to have created Taijiquan (or Tai Chi Chuan). Tai ji followed a different approach in its use of Qigong than did Shaolin. While Shaolin emphasized Wai Dan (External Elixir) Qigong exercises, Taiji emphasized Nei Dan (Internal Elixir) Qigong training. Later, in the Southern Song dynasty (1127-1279 A.D.), Marshal Yue Fei was credited with creating several internal Qigong exercises and martial arts. It is said that he created the Eight Pieces of Brocade to improve the health of his soldiers. He is also known as the creator of the internal martial style Xing Yi. Eagle style martial artists also claim that Yue Fei was the creator of their style.
