In Chen style Tai Chi there is one principle that underlies everything else. Not a technique, not a posture, not a training method. A principle. And once you understand it clearly, not just intellectually but in your body and in your daily life, the entire practice begins to make sense in a way that it cannot before.
The principle is this: Never try to control anything outside of yourself. When you do, you are out of balance.
This sounds simple. It is not. Working out what it actually means, in practice and in life, is the work of a serious student.
Balance and Stillness
To understand the principle we first need to understand what balance means in the context of Tai Chi, because it means something more specific than the everyday word suggests.
Think of a scale in perfect equilibrium. When both sides are exactly balanced, the scale is still. There is no movement because there is no force pulling one side over the other. The moment one side receives more weight, the scale moves, seeking the new balance point. When it finds it, it becomes still again.
In Tai Chi, this perfectly balanced, still state is called Wuji. It is the state from which all practice begins and to which it continuously returns. Wuji is not passive inactivity. It is the active, dynamic equilibrium of a system in perfect internal balance, present, released, available, with nothing pulling it in any direction unnecessarily.
Before every practice session, we stand in Wuji. We take the time to release tension, quiet the mind, balance the weight evenly through both feet, and find that still point. We are not waiting to begin. We are already practicing. The quality of everything that follows depends on the quality of this beginning stillness.
For the complete method of Wuji practice and what it develops, read Wuji: The Complete Standing Method and Wuji: The Art of Stillness.
What Happens When Balance Is Disturbed
Now an external force arrives. Another person applies pressure, a push to the shoulder, a grab at the wrist, a strike toward the face. The state of stillness is disturbed. The equilibrium is broken.
The normal human response to this disturbance is resistance. We brace against the force. We try to hold our position. We try to stop what is being done to us. This response feels like self-preservation. It is actually a loss of balance, because in resisting the external force we have made the external force the object of our attention and our effort. We are now trying to control something outside ourselves. And the principle tells us: when you do that, you are out of balance.
Moreover, if the person pushing is larger or stronger, resistance simply fails. The force overwhelms the resistance. We get pushed regardless, and we get pushed harder because our resistance created a battle between forces rather than a resolution.
The Tai Chi Response
The Tai Chi response to disturbance is not resistance and not collapse. It is something more precise and more interesting: movement that restores balance.
When force is applied, the question is not how to stop the force. The question is: how do I need to move to return to that balanced, still state? What movement will restore my Wuji?
The answer is always determined by the force itself. The direction, the speed, the quality of the force tells you exactly how to move in response. You go with the force, not against it. You move in the same direction at the same speed, neither faster nor slower, rotating through your waist to redirect the force along a spiral path that leads it away from your center and returns you to balance.
When this is done correctly, something remarkable happens. The person applying the force loses their own balance. They pushed expecting resistance. They found none. Their own force, unmet, carries them past their own center of gravity. They become unbalanced in the act of trying to unbalance you. And you are still standing in Wuji.
Grandmaster Wang Xi’an, under whom I trained for ten years in Chen Village, described the spirit required for this as: outside complete calm, inside like water boiling up. The outer appearance perfectly relaxed and composed, the internal awareness fully awake and prepared for whatever comes. This is the state that Wuji practice develops and that the principle of never trying to control the outside makes possible.
The Role of Silk Reeling
The movement that restores balance, the response to external force that goes with rather than against, always takes the form of circles and spirals. This is not aesthetics. It is mechanics.
A straight line of force can be met and stopped by another straight line of sufficient strength. A spiral cannot be stopped in the same way because it is continuously changing direction, continuously moving the point of contact, continuously redirecting the incoming force along a curved path that leads away from the center rather than into it.
This spiraling movement is called silk reeling, and it is the foundational movement principle of Chen style Tai Chi. Every movement in the practice, from the simplest weight shift to the most complex martial technique, is an expression of silk reeling. And every expression of silk reeling is an application of the principle: move in response to what is present, maintain your balance, let the spiral do the work.
For a complete understanding of silk reeling, read The Complete Guide to Silk Reeling. For the foundational exercises that develop it, see Silk Reeling Exercises for Beginners.
From Wuji to Tai Chi and Back to Wuji
The complete arc of Tai Chi practice can be stated simply: from stillness, through responsive movement, back to stillness. Wuji to Tai Chi to Wuji.
We begin in Wuji. A force arrives, internal or external, and we move in response, maintaining balance throughout the movement, never trying to control the force but always responding to it with exactly what is needed to restore equilibrium. When the movement is complete, we return to Wuji. Still, balanced, present, ready for whatever comes next.
This is not only a description of martial practice. It is a description of how the practice trains the nervous system to respond to everything. The body that has practiced this principle for years develops a genuine responsiveness, a capacity to feel what is present and respond appropriately, that extends far beyond the training floor. The practitioner who has internalized this principle moves through the world differently, with less unnecessary effort and more genuine effectiveness, because they have stopped trying to control what is outside themselves and learned to simply respond to what is actually there.
I cover how this principle develops through the complete form in my Tai Chi Form course, where each movement is taught in the context of the principle it expresses, so the form becomes comprehensible rather than merely memorized.
Two Training Methods, One Principle
Chen style Tai Chi develops this principle through two complementary training methods that test it from different angles.
Solo form practice is where the principle is first internalized. Moving through the form, the practitioner is continuously working with internal forces, the weight of the body, the momentum of the limbs, the demands of balance and transition. Every posture and every transition is an opportunity to apply the principle: do not try to force the movement, respond to what is present, maintain balance throughout. The form practiced this way is not choreography. It is a continuous moving meditation on the yin-yang principle.
Push Hands, or Tuishou, is where the principle is tested against an external force. Another person provides pressure, and the practitioner’s task is to respond without resisting, to move in coordination with whatever force is applied, to maintain balance while the partner loses theirs. What the solo form develops in isolation, Push Hands tests in relationship. The two methods are genuinely complementary. The principle understood in solo practice reveals its gaps and refinements in Push Hands. The corrections made in Push Hands deepen the quality of the solo form. Together they develop something that neither produces alone.
For more on how the complete Chen style practice develops through these methods, read The Complete Guide to Chen Style Tai Chi and Chen Tai Chi First Routine.
Sensitivity: The Missing Ingredient
The principle of never trying to control the outside requires something that most people do not initially have and must develop through practice: sensitivity. Specifically, the ability to feel exactly what force is present, in what direction, at what speed, with what quality, and to respond to that precise reality rather than to what you expect or fear or want to happen.
This sensitivity is trained through the practice of fangsong, the fundamental requirement of releasing all unnecessary tension from the body. A tense body cannot feel. Chronic muscular contraction acts as insulation between the nervous system and the reality of what it is receiving. When the body is genuinely released, when fangsong is present throughout, the mechanoreceptors in the joints and muscles send clear, unfiltered signals about exactly what is happening. The practitioner can feel the force the moment it begins, before it has developed into something requiring significant response, and move with it from the very beginning of its application.
Developing this sensitivity is one of the primary purposes of Wuji standing practice. Standing in released alignment with eyes closed, feeling the breath, feeling the weight distribution, feeling the subtle continuous adjustments of balance, trains the nervous system to receive information from the body with increasing precision. Over months and years of daily practice, this sensitivity extends outward. The practitioner begins to feel the quality of another person’s structure and intention through the point of contact before significant force has been applied. This is the foundation of genuine Tai Chi martial skill, and it is also the foundation of the responsive, balanced quality of movement that makes the health benefits possible.
For the complete development of this internal sensitivity through Wuji practice, see Wuji: The Complete Standing Method and Wuji and Zhan Zhuang.
The Principle in Daily Life
I want to be direct about something that is easy to miss if you read this only as martial instruction.
This principle applies everywhere. Not as a metaphor. As a practical observation about where balance is lost and found in human life.
How many times in a day do you try to control something outside yourself? Another person’s behavior. The outcome of a situation. What someone thinks of you. The traffic. The weather. The economy. The responses of other people to what you do and say. Each of these attempts at external control is, in the terms of this principle, a loss of balance. You have moved your attention and your effort to something you cannot ultimately control, and in doing so you have lost contact with the one thing you can: your own response to what is present.
The practice of this principle in daily life looks like asking, in any difficult situation: what do I need to do, how do I need to move internally, to return to my balanced state? Not how do I stop what is happening or control how it resolves, but how do I maintain my own equilibrium while responding appropriately to what is actually present?
This is a lifelong practice. It is also the one that makes every other practice more effective. For more on the foundational principles of Chen style Tai Chi, read The 3 Principles of Chen Tai Chi and The Complete Guide to Chen Style Tai Chi.
Frequently Asked Questions
What does Wuji mean and why does every practice begin there?
Wuji means something like undifferentiated stillness, the balanced state prior to movement and differentiation. In Tai Chi practice it refers to the specific internal state of perfect equilibrium, released, present, balanced, from which genuine Tai Chi movement can arise. Every practice begins in Wuji because movement that does not arise from genuine internal stillness is not Tai Chi movement in the meaningful sense. It is choreography performed over the top of habitual tension and imbalance. Wuji is not a pause before the real practice. It is the foundation without which the real practice cannot happen.
How does this principle relate to self-defense?
In self-defense application this principle is precise and testable. The practitioner who responds to an attack by resisting it is trying to control the external force, which puts them out of balance and, if the attacker is stronger, leads to failure. The practitioner who responds by moving to restore their own balance, going with the force and redirecting it through silk reeling movement, maintains their equilibrium while the attacker loses theirs in the act of attacking. The principle is not a philosophical preference. It is the most mechanically effective response to external force available, and it is why internal martial arts practitioners can neutralize force from much larger and stronger opponents.
Why is going with the force rather than resisting it so difficult?
Because resisting is the instinctive response to threat. The nervous system’s fight-or-flight response produces a reflexive bracing and resistance when force is applied. Overriding this reflex and replacing it with the responsive, balanced movement of Tai Chi requires years of specific training. The silk reeling exercises and push hands practice are designed precisely to develop this new reflex, to make the responsive movement as automatic as the resistant one currently is. It takes time and qualified instruction. It does not happen from understanding the principle intellectually.
Can this principle be applied by beginners or is it only for advanced practitioners?
The principle can be understood and worked with from the very first session. In fact, beginners who understand the principle clearly from the beginning develop faster than those who do not, because they know what they are trying to develop rather than just learning movement shapes. The application deepens with experience, the subtlety and precision of the response improves over years, but the principle itself is accessible from day one. Apply it first in your Wuji standing, releasing the resistance in your own body. Then apply it in the silk reeling exercises. The martial application comes later, but the principle is the same throughout.
