‘Ki belongs to the realm of feeling, not to that of knowledge.’1Tsuda Itsuo, The Non-Doing, Chap. II, 2013, Yume Editions (Paris), p. 27 (1re ed. in French, 1973). Tsuda Itsuo
As soon as you mention ki, you are dismissed as a mystic, a kind of crackpot: ‘It’s not scientific; no instrument or machine is capable of proving or demonstrating that ki exists.’ I completely agree. Indeed, if we consider ki to be a super-powerful energy, a kind of magic capable of throwing people across the room or killing them with just a shout, as was believed with kiai, we risk expecting miracles and quickly becoming disappointed.
Is ki an Eastern philosophy?
What is this “Eastern” philosophy that we supposedly do not have access to? Is there a specific domain reserved for a select few adepts, a handful of hand-picked disciples, or is this knowledge available to everyone, and what is more, without complicating our lives? I mean by leading a normal life, without being part of an elite group with access to secret knowledge, without having special, hidden practices that are doled out sparingly, but more simply by having a job, children, etc. When you practice Aikido, you are obviously engaged in both philosophical and practical research, but it is an “exoteric” rather than “esoteric” research.
Tsuda Itsuo wrote nine books, thus creating a bridge between East and West to enable us to better understand the teachings of Japanese and Chinese masters, to make them more concrete, simpler, and accessible to all. You do not have to be Eastern to understand and feel what it is all about. But it is true that in the world we live in, we are going to have to make a little effort. We need to break out of our habitual behaviours and references. We need to develop a different kind of attention, a different kind of concentration. It is not a question of starting from scratch, but of orienting ourselves differently, of directing our attention (our ki) in a different way.
First, we must abandon the very Cartesian idea that ki is one single entity, when in fact it is multiple. We must also accept that our bodies are capable of sensing things that are difficult to explain rationally, but which are part of our daily lives, such as sympathy, antipathy, and empathy. Cognitive science attempts to dissect all this using mirror neurons and other processes, but this does not explain everything, and sometimes even complicates matters.
In any case, there is an answer to every situation, but we cannot analyse everything we do at every moment in terms of the past, present, future, politics, or the weather. Answers arise independently of reflection; they arise spontaneously from our involuntary responses. Whether these answers are good or bad, analysis will tell us after the fact.
Ki in the West
The West was familiar with ki in the past; it was called pneuma, spiritus, prana, or simply vital breath. Today, this seems rather outdated. Japan has retained a very simple use of this word, which can be found in a multitude of expressions, which I will quote below, taking a passage from a book by my master.
But in Aikido, what is ki?
If any school can and should talk about ki, it is the Itsuo Tsuda School, not because we claim exclusivity, but simply because my master based all his teaching on ki, which he translated as breathing. That is why he spoke of a ‘School of Respiration’2ibid., Chap I, p. 17: ‘By the word respiration, I do not mean the simple bio-chemical process of oxygen merging with haemoglobin. Respiration is all at once vitality, action, love, a sense of communion, intuition, premonition, and movement.’3ibid., p. 16
Aikido is not a art of fighting, nor even a form of self-defence. What I discovered with my master was the importance of coordinating my breathing with my partner as a means of achieving a fusion of sensitivity in any situation. Tsuda Itsuo explained to us through his writings what his master Ueshiba Morihei had taught him. To convey this to us in a more concrete way, during what he called “the first part” – solitary practice, which we would now call Taisō – he would say KA when inhaling and MI when exhaling. Sometimes he would explain to us: ‘KA is the root of the Japanese word for fire, kasai, and MI is the root of the word for water, mizu.’4[see e. g. Tsuda Itsuo, The Science of the Particular, chap. XVIII, 2015, Yume Editions, p. 152–3 (1st ed. in French, 1976, p. 157–8)]. The alternation of inhalation and exhalation, their union, creates kami, which can be translated as the divine. ‘But be careful,’ he would tell us, ‘we are not talking about the God of Christianity or of any other religion – if you are lacking reference points, we could say that it is God the universe, God nature, or simply life.’
In the dojo, there was a drawing in Indian ink by Master Ueshiba containing fourteen very simple shapes and which we called Futomani because O-sensei had said that it had been dictated to him by Ame-no-Minaka-nushi: the Celestial Center. Tsuda Itsuo explains this in his book The Dialogue of Silence5Tsuda Itsuo, The Dialogue of Silence, chap. XII, 2018, Yume Editions, p. 106–7 (1st ed. in French, 1979, p. 157–8). Thanks to this, I gained a better understanding of the directions ki took when it had a form.

Reconnecting, rediscovering the links with what already exists deep within us
The founder spoke of Haku no budo and Kon no budo: kon being the essential soul that must not be stifled, but, he said, we must not neglect the haku soul, which ensures the unity of the physical being.6[see e. g. The Dialogue of Silence (op. cit.), chap. XII, p. 100–2; or The Way of the Gods (2021, same author & publisher), Chap XIII, p. 103–4]
Once again, we are talking about unity.
If our practice is called Ai-ki-do – “the way of unifying ki” – it is because the word ki has meaning.
Practical experience will allow us to understand this better than long speeches. And yet we must try to explain, try to convey this important message, because without it our art risks becoming a fight where “may the strongest, the most skilled, or the most cunning win,” or an esoteric, mystical, elitist, even sectarian dance.
And yet we know ki well; we can sense it from a distance. For example, when we walk down a small street at night and suddenly feel a presence, a gaze on our back, and yet there is no one there! Then suddenly we notice a cat watching us from a nearby rooftop. Just a cat, or a curtain that flutters surreptitiously. The gaze carries a very strong ki that everyone can feel, even from behind.
One of the practices of Seitai-dō called Yuki consists of placing your hands on your partner’s back and circulating ki. This is not about laying hands on someone who is, on the face of it, not sick to heal them, but about accepting to visualise the circulation of ki, this time as a fluid, like flowing water. At first, neither person feels anything, or very little. But then, little by little, they discover the world of sensation. You could say that it is a dimension in its own right, in all its simplicity. It is simple, it is free, it is not linked to any religion, it can be done at any age, and when you begin to feel this flow of ki, the practice of Aikido becomes so much easier. The kokyū hō exercise, for example, cannot be done without kokyū, and therefore without ki, unless it becomes an exercise in muscular strength, a way of defeating an opponent.
I would never have been able to discover the Aikido that my master taught if I had not willingly and stubbornly sought it out. In sensitive research, through all aspects of daily life, to understand, feel, and expand that understanding without ever giving up.
Atmosphere
Ki is also atmosphere, so in order to practice, you need a place that allows ki to flow between people. In my opinion, this place, the dojo, should, whenever possible, be “dedicated” to a particular practice or school. Tsuda Itsuo believed that entering the dojo was a sacred act, which is why we bowed when stepping onto the tatami mats. It is not a sad place where people ‘should wear a scowling constipated expression. On the contrary, we must maintain a spirit of peace, communion and joy.’7Tsuda Itsuo, Heart of Pure Sky (posth.), ’Booklet n°3 – Respiratory Practice in Aikido’, 2025, Yume Editions, p. 102 (1st ed. in French, 2014)
The atmosphere of the dojo is nothing like that of a club or a multi-sports hall that is rented for a few hours a week and used, for reasons of profitability, by different groups that have nothing to do with each other. The kind of place, the kind of gym where you go, train, then take a shower and say goodbye; at best, you might have a beer at the local bar to chat a little with each other. When you know about ki, when you start to feel it, and especially when you want to discover what lies behind this word, a place like the dojo is really something else entirely. Imagine a quiet place in a small Parisian passageway at the end of the 20th arrondissement. You cross a small garden and on the first floor of a very simple building is “The Dojo.”8[more of which in Yann Allégret, On the wach for the right moment, pub. online (Feb. 2014)]

You can come every day if you want, because there is a session every morning at quarter to seven: you are at home. You have your kimono on a hanger in the changing rooms, the session lasts about an hour, then you have breakfast with your partners in the adjoining area, or you rush off to work. On Saturdays and Sundays, you can sleep in, with sessions at eight o’clock.
Explaining ki is difficult, which is why only experience allows us to discover it. And for that, we must create the conditions that allow for this discovery. The dojo is one of the elements that greatly facilitates the search in this direction. It reconnects circuits, but also unties the bonds that constrain us and obfuscate our vision of the world.
Little by little, the work will be done, the knots will be untied, and if we accept that they are untied, we can say that the ki begins to flow more freely again. At that moment, it flows as vital energy; it is possible to feel it, visualise it, and in a way, make it conscious. Unnecessary tensions that cannot be released cause our bodies to stiffen. To make this as clear as possible, we could say that it is a bit like a garden hose that is blocked. It risks bursting upstream. The stiffening of the body forces it to react for its own survival. This triggers unconscious reactions that act on the involuntary nervous system. To avoid these blockages, micro-leaks of this vital energy occur, and sometimes even larger leaks, for example in the arms, at the koshi, and mainly at the joints. The immediate consequence is that people are no longer able to practice with fluidity, and it is strength that compensates for the lack. Parts of the body stiffen and begin to react like bandages or casts to prevent these losses of vital force. This is why it is so important to work on feeling the ki, on making it circulate. At first, visualisation allows us to do this, but as we deepen our breathing (the sensation, sensitivity to ki), if we remain focused on flexible practice, if we empty our minds, we can discover, see, and feel the direction of ki, its circulation. This knowledge allows us to use it, and the practice of Aikido becomes easy. We can begin to practice non-resistance: non-doing.
Women’s natural sensitivity to ki
Women generally have greater sensitivity to ki, or more accurately, they retain it more if they do not distort themselves too much in order to defend themselves in this male-dominated world where everything is governed by the criteria and needs of masculinity, the image of women that is conveyed, and the economy. Their sensitivity stems from the need to keep their bodies flexible so that they can give birth naturally and care for newborns. This flexibility cannot be acquired in gyms, weight rooms, or fitness centres; rather, it is a tenderness, a gentleness that can be firm and unwavering when necessary. Newborns need our full attention, but they cannot say ‘I’m hungry, I’m thirsty, or I’m tired,’ or ‘Mom, you’re too nervous, calm down, and tell Dad to speak more softly, it scares me.’
Thanks to their natural sensitivity, they sense the child’s needs, they intuitively know what to do, and ki flows between mother and child. When the father, who is always very rational, does not understand, the mother senses and therefore knows. Even if she is not a mother, even if she is a young woman with no experience, it is the body that reacts, it is the body that has this natural sensitivity to ki, and that is why, I think, there are so many women in our School. It is because ki is at the centre of our practice that nothing can be done without it. We focus our sensitivity in this direction and thus we can see the world and people not only on the level of appearances but much further, in their depth, what is behind the form, what structures it, or what drives it.
Some examples by Tsuda Itsuo, taken from The Non-Doing
Most Japanese themselves are incapable of explaining what ki is, yet they know instinctively when to use the word and when not.’9The Non-Doing (op. cit.), Chap. II, p. 25–7
Tsuda Itsuo started practising Aikido at the age of forty-five. He was not athletic, but his mere presence transformed the entire atmosphere of the dojo. I would like to tell you a story about one of the exercises I did in the 1970s, when my master was already over sixty years old. When I passed through the gate to the courtyard at the back of which the dojo was located, I would stop for a moment, close my eyes, and try to sense whether “he” was there. At first, it did not work very well; it was just random guesses, strokes of luck. Little by little, I understood: I should not try to know. So I began to “empty” myself, to stop thinking, and it came. Every morning, I knew whether he had arrived or not. I could feel his presence as soon as I approached the dojo.
From that moment on, something changed in me. I had finally understood a small part of his teaching, and above all, I had verified that ki was not part of the irrational, that it was concrete, and that its perception was accessible to everyone since it had been accessible to me.

The Aikido founder’s desire was to bring human beings closer, to him the world was like a big family:


The event, organized by the Scuola della Respirazione in collaboration with the Central Municipal Library of Milan, took place in front of a large and attentive audience. After a short video presentation on the philosophy and thought of Master Tsuda, some practitioners of the Scuola della Respirazione read a selection of excerpts from The Path of Less.Later, Régis Soavi, host of the evening, by answering to the questions of the interested public, talked about his experience on the importance of the practice philosophy and Itsuo Tsuda books may have in everyday life.The organization of the evening has involved a lot of us and it was an interesting exchange with the library staff, who contributed to the unfolding of the evening with care and sensitivity.Click on photos to enlarge


Here the second of the Six Interviews of Itsuo Tsuda “Breathing living philosophy” by André Libioulle broadcast published on France Culture in the 1980s.Broadcast # 2Q: During the second week we will talk more in dept about the books published by Itsuo Tsuda. All these works published by the “Courrier du Livre” in Paris, are currently six: “The Non-Doing”, “The Path of Less”, “The Science of the Particular “, a book with the title “One”, “The Dialogue of the Silence ” and recently “the Unstable Triangle”. They relate to breathing and the field of thought in relation to it. […]The concepts of soul and body has always been separated into clear-cut by the west. They have often talked about the elevation of the individual’s soul as much as underestimating the body, considered as related to temptation. If for Plato, the soul is cramped in its carnal envelope, a prisoner of the body, for a man like Itsuo Tsuda the body appears to be the captive of the soul. A soul who constantly manipulates abstractions and cuts the vital impulse.The man more and more lives in the brain. The hopes of the society is based on the intensive exploitation of intellectual capacity in which it is seen the privilege of the human being. But this hypertrophicity of the brain creates a gap that is the source of the imbalance between the sensations, the body as life, as energy, as momentum, and the world built, conceptualized cerebrated. Breathing is unification, return to self, if you release the separation body and soul, if the soul ceases to be an abstraction, then it is everywhere, it is in the body as well as outside.So… “ki”, the concept of which we gave already a hint during the previous broadcasting, introduces us to the idea of unity. This is what we will try to understand now. So, Itsuo Tsuda, it seems that the first step, towards the understanding of ki, it is whether we feel the sensation. That is to say not to abstract it, not to imagine about living a sensation but really and truly feeling it.I.t.: There is a principle we recognize in Chinese medicine, it is: cold head and warm feet. Currently it is exactly the other way around: hot head and cold feet. We do not even feel our feet. And the head heats up more and more. There is quite a contributing factor to it: this is Westernization. But we can not turn back. This is a trend that has been going on since long time already. But we also have the obvious benefits that come from Westernization. But if that is only on a material level it does not helps us, it places us in a precarious state as individuals. Individuals become increasingly prisoners of well-planned structures, they can not feel alive themselves anymore.Q: Europeans elsewhere, you write, need to understand before acting. They do not engage immediately in action.I.t.: What I am doing here, it is not precisely the same as what we would do in Japan. Often in Japan we do not explain, we found ourselves immediately into the experience path, it’s up to everyone to learn the lesson, isn’t it. Well, in the West this does not work. We need to understand first. But understanding is not enough. I have explained those people who were listening the explanation about swimming, but this does not allow people to be able to dive into the water. If we have not felt the first touch of the water, one can fill his head with all sorts of explanations, but it is useless.Q: But people will perhaps argue about this, “but why do I need to be able to feel? Why is that so important for me? “I.t.: Well, this is the concept of “Seitai” precisely that one that Noguchi created after the war. At the moment people think in a dualistic way: “here – that is good, that is bad. We must fight the evil. When we have fought the evil, we will have the good. ” But in fact, we do not search this: we nomalize the terrain. That’s what he called “Seitai”: a well harmonized body. In the West we keep on finding the cause, we try to exterminate the cause. But as soon as we finished with the cause, here there are other causes that arise. But that’s the method that complies with this mental structure. But Noguchi brought this view which is quite different, which transcends all. If your organism is normalized, the problem itself becomes less important. In the West we say: there is such a problem. That’s a way of defining it, it does not change volume, it’s still there. We must attack this way etc.Q. So there is in fact for the West an anatomical way of understanding, discursive kind, in which we distinguish cause and effect and in order to be able to act on a particular item. The concept introduced by the Seitai is a different concept. It is the notion of sensation. But this is the notion, if I understand, in which knowledge is not excluded. But it is another type of knowledge, intuitive knowledge, qualitative I would say, in relation to the Western notion of measure or quantification.I.t.: The same problem increases or decreases importance depending on sensation. A bottle is half empty or half full. But the quantity is exactly the same. But the sensation is different in both cases. So just a little nothing can change human behavior. If one says, “that’s it, I’m done,” from that moment on one can no longer move forward. While if I say “I have already made three steps forward,” then Iam ready to make a fourth step, isn’t it.Q. Do you not think that there is a notion that is brought by the West, which is about the total or the global but understood as an assembly of parts? With the quality we are also in something global, but without this assembly idea.I.t.: In Seitai, we do not look at a person as an assembly of various parts. That’s the basic idea. A person is an individual, total, isn’t it. But everyone is different, in its movement, in his breath, in his sensitivity. That’s what matters to us.Q. You talked about Master Noguchi repeatedly. Could we try to understand what the whole is, the unit in an individual through some examples of the practice of Master Noguchi, Noguchi was a therapist, wasn’t he. He is the creator of the Seitai method. So how is his job? What enabled him to understand those concrete things, spontaneously?I.t.: For example, each one has its own biological speed, which determines the behavior, actions, movements etc. It is viewed in a quite detached way, objective, as per minute etc., etc., but for Noguchi, well that’s something concrete. Everything comes from that biological speed that is inherent in the individual. Without this notion of speed he can do nothing. But this
Q: … so there, the notion of speed has nothing to do with the notion of rapidity, for example …I.t. … no, no …Q: … as we know it, it’s something else …I.t.: No. We need to create the contact with the biological speed of that particular person. No need to apply a general and objective speed. Well, for example, there is a kid who comes while crying, he is crying because he broke his arm. Parents say: “It is impossible to touch him, he keeps on crying and crying …”. But Noguchi has already touched him. “Ah, ah good then it is because he does not dare to cry in front of a master.” No it’s not that. He touched him at a , biological speed, the breathing speed of the child, which is peculiar to him. At that time, the kid does not feel the contact, it’s part of him, and that it’s so important.[Read extracts from books Itsuo Tsuda]Q. You wrote that Master Noguchi could identify the individual through observation and by touch, something like the notion of an unconscious movement.I.t.: Yes, for him, all the movements are unconscious hundred percent. We believe precisely the opposite. We believe we are the masters of ourselves, but we can not do much, and we try to hold us, to behave in front of others, etc. And then one day the brake is released, and then we wonder where it comes from. For Noguchi everything is unconscious, we are not masters of ourselves.Q. Did Mr. Noguchi made a distinction between the unconscious movement and posture …I.t. … but the posture is the realization of the unconscious movement.Q. So the posture, it is observable by everyone … from the outside, without preparation, while the unconscious movement itself, requires preparation.I.t.: Posture, if you think about the military way, for example, “Attention!” etc., so everybody tries to do pretty much the same. But when one is at rest, everyone is different.Q. What is the relationship there between breathing and unconscious movement?I.t.: There are some people who are breathless, for example. So when this happen, respiration rises higher and higher. So, people breathe from the top of the lungs and then finally when their breath weakens it goes through the nose. What we do it is to go lower, right, so we can breathe with our belly, or, if one’s wants, with the feet. Without the practice it is quite difficult to explain that.Q: The idea of ??breathing is a concept much broader than a simple biochemical deal. Breathing is life, it is ki …, the “souffle” , the soul …I.t.: yes …








live in a society where you go to bed very late and you get up very late too. In my case I really love the morning. One can be tired in the evening, people after working hours are stressed. Sessions of martial arts then very easily turned into a relief valve, and so on. Rather in the morning, competitiveness does not have too much importance … you get up, you are in the dojo, you can easily breathe, you start your day. Furthermore we are very lucky to be in a permanent dojo. One comes and it is like being at home, in an association but at home, the dojo are used only for this reason. There are gyms with more or less clean changing rooms where you can not even leave your watch otherwise they might stole it, and so on. So you come here in the morning, take a little coffee, tea, and then practice. And so the day begins and starts well, it is a real pleasure. Every morning I have a great pleasure to see people getting there and taking their time, we are in a world where we do not take our time anymore…
