Tai Chi is a system of slow, gentle, graceful movements combined with meditation. It can be used either for self-defense, health, or aesthetics. Breath control is a vital element of this practice. Weight and pressure are made to sink down to what is called in Zen the Hara Centre (near the solar plexus). This system belongs to Chinese Taoism.
