Principles
Theory of the Internal Arts
The internal arts rest on a small set of concepts: the movement from stillness (wuji) into taiji, the standing postures that train the body to find that stillness, and the paired exercises that test it against a partner. Each study defines its concept, traces its sources, and connects it to the forms and texts where it appears.

Screen One
Start at the root
Every internal arts theory chain begins with wuji — the undifferentiated stillness from which taiji, and therefore movement, emerges. The concept study traces the term from its Song-dynasty source to its place in the Taiji curriculum.
Screen Two
The trained methods
From stillness the studies move to method: how the body stands, how it meets a partner, and how the classical formulae name the energies a practitioner is learning to feel.
Theory Concept
Standing Meditation
Standing meditation (站樁) — the post practice: Wang Xiangzhai's embrace posture, the Bajiquan two-powers post, and the stillness before Taiji.
Theory Concept
Push Hands
Push hands (推手, tuishou) is Tai Chi's two-person practice: listening energy, the eight gates, the classic Da Shou Ge, and the rules that govern contact.
