Qi

Qi (Also spelled Chi, Ki), and pronounced “chee”, is the Chinese term for vital energy or life force, found in all living things and formed from the interaction of the energies of Yin and Yang.

Chinese medical thinking does not distinguish between matter and energy. Qi is thought to be energy at the point of becoming matter. Some traditional Chinese medicine theories describe Qi as the energy that is present in the meridians and the bodily organs.
