The Teacher Who Knows vs. The Teacher Who Embodies
Two instructors demonstrate the same technique. Both can explain the biomechanics. Both can name the principle. Both can correct obvious errors. When a master-level practitioner watches them, one receives a nod of recognition. The other receives polite acknowledgment.
The difference is not knowledge. It is embodiment.
I recognise this gap in myself. Most techniques I can explain clearly still feel mechanical when I demonstrate them. Occasionally, something shifts and a technique flows differently, a glimpse of what embodiment might be. This gap between knowing and embodying shapes what we can transmit to students.
Two Different Types of Understanding
When I know a technique intellectually:
- I can explain the principles
- I understand what should happen
- I can analyse movement theoretically
- I can describe correct form
- I can identify obvious errors
This is real competence. I can help students reach understanding and decent execution. Many of us teach primarily from this level for many techniques.
But there are limits:
- Subtle elements remain invisible to me
- I think through movements rather than moving naturally
- Unexpected situations throw me off
- I teach "what" better than "how"
When I embody a technique:
- My body has internalised the movement
- Technique flows without conscious thought
- Response is natural and automatic
- I perceive subtleties I could not see before
- Movement IS the knowledge
The embodied practitioner demonstrates something words cannot transmit. Other experienced practitioners recognise it immediately. They may not articulate what they see, but they see it.
Signs that suggest embodiment:
- I cannot always explain WHY something works, but I know it does
- Technique emerges naturally under pressure
- I discover new applications without being taught them
- My body corrects itself before my mind notices
How This Shapes Teaching
We can only take students as far as our own understanding of a particular technique.
From knowing, I can:
- Bring students to intellectual understanding
- Teach correct form and basic execution
- Identify obvious errors
- Produce competent practitioners
From embodiment, I can also:
- Perceive subtle errors I would otherwise miss
- Demonstrate depths that draw students forward
- Teach from felt experience, not memorised explanation
- Show students what further development looks like
Students under a teacher who only knows a technique may never see what embodiment of that technique looks like. They may reach competence and believe they have arrived.
Teaching from knowing produces demonstrations that look correct. They match the form. They accomplish the technique. An observer without deep experience cannot distinguish them from embodied demonstration.
But experienced practitioners see:
- Initiation from extremities versus centre
- Conscious processing versus natural flow
- Memorised sequence versus spontaneous response
- Effort versus effortlessness
The knowing demonstration teaches students to copy external form. The embodied demonstration transmits something beyond form.
Self-Assessment
I find it useful to ask myself, for each technique I teach:
- Can I execute this under pressure, with resistance, without thinking?
- When I demonstrate, am I recreating a pattern or moving naturally?
- Can I adapt this spontaneously to variations I have not trained?
- Have I discovered aspects of this technique through practice that I was never taught?
For most techniques, I answer "no" to at least one of these. That tells me I know the technique but have not embodied it.
No one embodies every technique equally. Even masters have techniques they perform from competence rather than mastery. Our level with each technique reflects how much we have practiced it, how well we were taught it, and how our body responds to it.
I am at different levels for different techniques. The ones I have drilled thousands of times feel different from the ones I practice occasionally. Ikkyo feels closer to natural than yonkyo. Shomen-uchi ikkyo omote feels different from shomen-uchi ikkyo ura, same technique, different levels of internalisation.
For most of us, the mix looks something like:
- Perhaps a few techniques approaching embodiment, where we can teach with some depth
- Many we know adequately, we can teach competently
- Some we know, we teach basics and acknowledge limits
- Some we do not enjoy teaching
The question is not whether we have embodied everything. The question is whether we know where we are with each technique we teach.
The Demonstration Robotization Trap
A peculiar thing happens to aikido teachers over time: movement becomes increasingly rigid. New teachers often demonstrate with fluidity. Long-term teachers often demonstrate with mechanical precision. This is backward from what experience should produce.
How it happens:
- Teacher begins with fluid technique
- Teaching requires demonstration for beginners
- Good demonstration for beginners means: stopping at key points, showing positions clearly, repeating exactly
- Teacher demonstrates dozens of times per class
- Muscle memory shifts toward demonstration style
- Teacher's own fluidity degrades
- Students learn rigid style from rigid demonstration
The conflict:
- Fluid technique requires continuous flow, no stops, natural transitions
- Demonstration requires clear positions, holds for observation, repeatable patterns
These are opposite movements. Practicing demonstrations means practicing rigidity.
Breaking the cycle:
In teaching:
- Reduce demonstrations - describe more, show less
- When demonstrating, move naturally rather than stylising
- Demonstrate once or twice, not ten times
- Let students explore rather than copy exactly
In personal training:
- Maintain practice time separate from teaching
- Practice at your edge, not at demonstration level
- Seek training with teachers who challenge you
- Notice if you feel rigid after teaching
- Weapons training helps maintain fluidity
Tony Sargeant's "Technical vs. Just Knowing"
Traditional Iwama teaching uses different language for this distinction. Tony Sargeant, 7th Dan Shihan and head of Takemusu Iwama Aikido, speaks about "technical" versus "just knowing."
His words: "I can do kata mechanically - so there's the technical and there's the just knowing. I don't expect you to get it."
His language maps to:
- "Technical" = Knowing
- "Just knowing" = Embodied
"I don't expect you to get it" acknowledges that this transition takes specific work.
Sargeant identifies what crossing from technical to embodied requires.
Ego death: "I don't need to win anymore." The competitive need to demonstrate superiority prevents the letting go required for embodiment.
Letting go of control: "I don't need to be in the right place anymore." Rigid correctness prevents natural response.
Soft wall development: complete removal of expected resistance.
Time and repetition: until movements are automatic.
Permission to forget form: once internalised, stop thinking about it.
These requirements explain why many practitioners remain at the technical level. Continuing to train technique while avoiding the psychological work is easier.
What This Means in Practice
Teaching from knowing works. Most teaching involves students who need exactly what the knowing teacher provides: clear form, correct positioning, basic mechanics. Teaching from knowing helps students. It has value.
The difficulties arise when:
- I mistake knowing for embodiment in myself
- I stop my own training because I think I know enough
- I cannot acknowledge to advanced students what I have not yet embodied
Teaching from embodiment is different. This is not superiority, it is different capacity. I might embody ikkyo but only know sankyo intellectually. Each technique gets taught from my actual level with that technique.
Conclusion
The difference between knowing and embodying is not degree. It is kind. Both have teaching value. Only embodiment transmits the depths that create the next generation of embodied practitioners.
The work continues. Training the techniques I know, working toward embodiment. Trying to teach appropriately from where I actually am with each technique. Trying to keep developing rather than settling.
The destination has a name: takemusu aiki - where technique emerges spontaneously, without thought, appropriate to the moment. We are all somewhere on this path.
