GrandMaster HUANG - 13 Questions and Answers - Question 6

Q6. Is it correct to have either high or low postures in the set movements of Tai Chi?
The art of Tai Chi does not distinguish high and low postures, but is rather based on the idea of four "balances" or equilibriums:
1. balance in the magnitude of the posture or movement such as both sides of the body must have a "balanced" amount of spatial displacement when moving;
2. accuracy or precision achieved simultaneously by all parts of the body;
3. bodily balanced when moving or turning;
4. steadiness, particularly when moving.

External and internal balance or harmony must be cultivated, so there is no slanting of the central axis of the body. when hind force is invoked, the hind knee being bent will move up or straighten slightly though the height of the body remains unchanged. This is so as consciousness (or intend) and Qi would "close" centrally instead of coming up while the bent knee is used to adjust accordingly. Consciousness is used to lead the muscles in relaxing. Joints, muscles and ligaments must then be loosened, relaxed and "thrown" open but still linked. The body is then erect and comfortable. Consciousness is also used to "move" Tai Chi principles to parts of the body. Having achieved "four balances and eight steadiness", the question of high and low postures is then answered individually.
