Muscle/Tendon Changing (Yi Jin) and Brain/Marrow Washing (Xi Sui) Qigong have been known in China since the Liang dynasty (502 a.d. ). However, they were kept secret, and only in the last fifty years has this knowledge gradually been revealed to the general public. Within a short period of time, these two arts have not only been widely adopted by Qigong practitioners, but they have also interested many Chinese medical scientists and bioscientists.
Muscle/Tendon Changing Qigong specializes in circulating Qi in the twelve primary Qi channels and the two major Qi vessels (Conception and Governing Vessels). The training will strengthen your physical body, including muscles and tendons, and maintain the smooth circulation of Qi in the primary channels and the internal organs, which is the key to maintaining health and slowing down the degeneration of the physical body.
Usually, after a practitioner becomes familiar with the Muscle/Tendon Changing Qigong, he/she will enter the deeper field of Qigong training, that of Brain/Marrow Washing. This teaches the practitioner how to fill up the Qi in the "eight extraordinary Qi vessels." In Chinese medicine, the vessels are considered reservoirs of Qi, and they regulate the Qi in the body’s primary Qi channels and organs. A strong and abundant store of Qi is the key to keeping your body healthy and extending your life. Theoretically, your body deteriorates as you age mainly because your blood loses its ability to feed and protect your body. The red and white blood cells are produced by your bone marrow, but as you grow older, the marrow becomes "dirty," and produces fewer and fewer useful blood cells. However, if you know how to "wash" the marrow, it will start, once again, to produce fresh, healthy blood. Your body will begin to rejuvenate itself, and restore itself to the glowing health of youth. Click to learn how Chinese medicine treats Contact Dermatitis.
Most important of all, the practitioner of Brain/Marrow Washing Qigong is able to lead Qi to his brain to nourish it, and to raise up his spirit. To the Daoists and Buddhists, Brain/Marrow Washing Qigong is the path to reach the final goal of enlightenment or Buddhahood. Part of Brain/Marrow Washing involves stimulating the sexual organs. In their thoroughness, the ancient Qigong practitioners discovered that, in addition to providing hormones, the genitals are also a potent source of the Qi which is necessary for the training.
