Remaining calm is a central tenant of taiji practice. The effort is within. The outward appearance should always be relaxed and flowing. The inner work requires strength and concentration.
Nei gu jing shen, wai shi an yi.
Strengthen the spirit inside, the outside is peaceful.
The spirit “jing shen” inside has two parts: jing – energy and shen – spirit. Through the internal arts and practice, we work to develop these two, along with xin 心 – heart, qi 气 – breath, and yi 意 – mind.
The outside refers to the outward appearance. The whole body, not just the facial expression, should be calm and relaxed, literally at peace.
