Tai chi   What is tai chi?  Tai chi is a gentle exercise program
that is a part of Traditional Chinese Medicine (TCM). Derived
from the martial arts, tai chi is composed of slow, deliberate
movements, meditation, and deep breathing, which enhance
physical health and emotional well being.  As are many practices
from the East, tai chi is based on spiritual and philosophical
ideas that advocate a need for balance in the body, mind, and
spirit. Central to tai chi is the idea that qi (pronounced
"chee"), or life energy, flows throughout the body. Qi must be
able to move freely for good health. The principle of yin/yang
is important, too. Yin and yang are opposite and complementary
forces in the universe, in the same way as light and dark are.
Tai chi is meant to harmonize these pairs of opposites. Finally,
tai chi imitates motion found in nature, such as the movements
of animals, thereby uniting human beings with the natural world.
