A Chinese term for life energy or spirit (Japanese ki), comparable
with the Hindu yoga term prana. Although deriving
from the breath, chi, like prana, is transformed by the metabolism
into subtle vitality that follows certain channels in the
body, and it is related to the state of health of an individual. In
the recently revived ancient Chinese systems of acupuncture
and acupressure, these subtle energy flows are modified by inserting
needles or by specific pressures at certain body points,
resulting in improved health or the alleviation of physical disorders.
In the Asian system of martial arts, chi is directed by willpower
to specific points of the body, resulting in apparently
paranormal feats of strength and control. (See also breathing)
