2 STYLES OF QI GONG
Generally speaking, all Qi Gong practices can be divided according to their training theory and methods into two general categories: external elixir (Wai Dan) and internal elixir (Nei Dan). Understanding the differences between them will give you an
overview of most Chinese Qi Gong practices:
External Elixir (Wai Dan, Wai Gong)
“Wai” means “external or outside,” and “Dan” means “elixir”, “gong” means “to practice”. Thus, Wai Dan Gong means the practice of building the elixir externally. External here means the limbs, as opposed to the torso, which includes all of the vital organs. Elixir is a hypothetical, life-prolonging substance for which Chinese Taoists have been searching for millennia. They originally thought the elixir was something physical that could be prepared from herbs or chemicals purified in a furnace. After thousands of years of study and experimentation, they found that the elixir is in the body. In other words, if you want to prolong your life, you must find the elixir in your body and then learn to protect and nourish it. In Wai Dan Qi Gong practice, you concentrate your attention on your limbs. As you exercise, the qi builds up in your arms and legs. When the qi potential in your limbs builds to a high enough level, the qi will flow through the channels, clearing any obstructions and nourishing the organs. This is the main reason that a person who works out, or has a physical job, is generally healthier than someone who sits around all day.
Internal Elixir (Nei Dan, Nei Gong)
“Nei” means “internal” and “Dan” means “elixir”, “gong” means ”to practice”. Thus, Nei Dan Gong means the practice of building the elixir internally. Here, internally means in the body instead of in the limbs. Whereas in Wai Dan the qi is built up in the limbs and then moved into the body, Nei Dan exercises build up qi in the body and lead it out to the limbs. Generally speaking, Nei Dan theory is deeper than Wai Dan theory and it is more difficult to understand and practice. Traditionally, most of the Nei Dan Qi Gong practices have been passed down more secretly than those of the Wai Dan. This is especially true of the highest levels of Nei Dan, such as Marrow/Brain Washing, which were passed down to only a few trusted disciples.
4 CATAGORIES OF QI GONG
Qi Gong can also be classified into four major categories according to the purpose or final goal of the training. This is only a rough breakdown, however, since almost every style of Qi Gong serves more than one of the above purposes. For example, although martial Qi Gong focuses on increasing fighting effectiveness, it can also improve your health. The Daoist Qi Gong aims for longevity and enlightenment, but to reach this goal you need to be in good health and know how to cure sickness:
1. Health Qi Gong for preventing sickness and maintaining health using breathing, stretching and meditation
2. Medical Qi Gong for curing sickness using herbs, massage and acupuncture
3. Martial Q Gong for energizing the body for sports and combat
4. Spiritual Qi Gong for energizing the brain for enlightenment or Buddhahood using all of the above particularly reverse breathing and stillness meditation.
