Tai chi offers an opportunity to look beyond the surface. To see not only what a practitioner is doing on the outside but deeper on the inside. Not usually an immediately obvious for a beginner. You have to develop skill to look within the other and yourself. It takes practice to see the depth of a practice. From where does movement originate? What is the underlying intention? What is nature and quality of the Qi (energy)?
About developing strong chi in the body
When Qi is strong and flowing freely in your body, you are healthy and full of energy. The teachers say that qi is yang energy. What is the corresponding yin energy to qi? Wouldn’t it be another form of qi? I perceive qi as a healing energy as opposed to a martial force. Yin qi creates the intention and affects the potential for yang qi. There is always something guiding qi from a center place of stillness and quietude.
