Qi (pronounced “chee").
Qi is energy
Qi is universal
Qi embraces all manifestations of energy, from the most material aspects of energy (such as the earth beneath your feet, and flesh and blood) to the most immaterial aspects (light, movement, heat, nerve impulses, thought, and emotion).
Life, it is said in the Chinese medical classics, is a gathering of Qi. A healthy (and happy) human being is a dynamic but harmonious mixture of all the aspects of Qi that make up who we are.
Qi is in a state of continuous flux, transforming endlessly from one aspect of Qi into another. It is neither created nor is it ever destroyed; it simply changes in its manifestation.
