It is also important to note the different types of disharmonious Ki in the body. Because the Chinese have extensive systems of Ki or Qi classification, I will use Chinese information about Qi to describe these types of disharmonies. The first broad category of Qi is Deficient Qi, which means that there is not enough Qi in the body or in a certain part of the body. Deficient Qi often makes a person lethargic and can affect the entire body. Within this broad category are a few sub categories such as Deficient Protective Qi, Deficient Organ Qi, and Collapsed Qi. Deficient Protective Qi is what Westerners call a weak immune system, which results in catching colds and flus frequently. Deficient Organ Qi means that a certain organ does not have enough Qi to function properly so it may fall into such a state of disharmony that it may slip out of place. Qi holds the organs in place so when a person has Deficient Organ Qi to an extreme extent, then Collapsed Qi can occur and the organ will fail to stay in its proper position. The other broad category of Disharmonious Qi is Stagnant Qi. This type of Qi means that the body's Qi is not flowing smoothly or is blocked. Stagnant Qi can cause aches or improper organ function. A sub category to Stagnant Qi is Rellious Qi, which is when Qi flows in the wrong direction. If any one of these Disharmonious Qi types inflicts upon an organ then particular problems occur. The symptoms of these problems are important to note once you know Reiki because Reiki can usually bring harmony back to disharmonious Qi. A section of The Web That Has No Weaver (1983) contains extensive information about these symptoms.
