My master Tsuda Itsuo, quoting Ueshiba O-sensei, wrote in his second book: ‘Aikido is an art whereby people unite and become separate again (musunde hanatsu)’ 1.
This was a very present aspect of his teaching, but he never used the terms awase and musubi. He spoke to us in French, he spoke about something greater than ourselves. He invited us to empty our minds in order to perceive something. Sometimes he would say: ‘God (in the sense of kami) is talking all the time, but we humans can’t tune in, so we don’t hear anything. Or we only hear sounds like a scrambled radio. But God speaks clearly’. So for him, it was up to us to put ourselves in a state where we could “receive”. The Itsuo Tsuda School’s aikido is based on what he called the fusion of sensitivity, so on fusing with the partner: faced with an attack, there is a response, but for our response to be adequate, we have to fuse with the partner. During the sessions I talk, for example, about merging and harmonising with the partner, feeling their centre – then we are bound by something, nothing is foreign to us any more. Today I am starting to go a bit further in the practice of aikido and I feel much more what Tsuda sensei meant about the link that unites us with the Universe. You really feel yourself like a link between this Universe and your partner, and you realise it circulates, that everything returns to the Universe.
The Respiratory Practice: a Musubi practice
The Respiratory Practice2 we do at the beginning of the session puts us in a “state of mind” that allows us to receive, to create this link between the Universe and ourselves. We do not really know what the Universe is. It is not the stars, it is not a black hole, etc. It is something else. For the Respiratory Practice we stay as close as possible to the teachings of Ueshiba O-sensei; Tsuda sensei was very precise about this.
For example, we do the vibration of the soul, Tama-no-hireburi, three times, each time with a different rhythm (slow, medium, fast) and only while breathing in. The first time we evoke Ame-no-minaka-nushi, the Centre of the Universe. I sometimes say this is an “invocation-evocation”. Ueshiba O-sensei used to say that it should be evoked three times during the vibration of the soul: the person leading the session says it out loud and then you evoke twice more internally. I heard this from Tsuda sensei, but nowhere else.

So when we evoke Ame-no-minaka-nushi, as Ueshiba O-sensei used to say, we place ourselves at the Centre of the Universe. Centre of the Universe does not mean “Centre of the World”, nor “me and others”, nor something religious. It is somehow elusive, but at the same time extremely concrete. In any case, it does not encumber us, it is the Centre of the Universe and we can be there.
Then the second time we evoke Kuni-toko-tachi, the Eternal Earth, for me it is human, it is matter. The first is immaterial, the second becomes concrete, it is matter.
Then the third Kami evoked-invoked is Amaterasu, the sun goddess, life, what animates us. I sometimes tell the story of the cave where Amaterasu took refuge and of the rock door3. Ueshiba O-sensei often told it and Tsuda sensei also quoted it. It is life which had shut itself away in a dark cave and which has re-emerged. It is important to open the rock door inside us. We have closed ourselves off, we have become rigid, we cannot hear anything, and then one day we open up a little bit.
Aikido gives us a breath of air, something that allows us to breathe a little better. Then, with this breath, we can open up more and perhaps hear better what the Kami have to say to us, what the Universe has to say to us. I am not religious at all, but every morning I recite the Norito, as Tsuda sensei did, as Ueshiba O-sensei did. Every morning, at the beginning of each session, at quarter to seven, I recite the Norito, then I do the vibration of the soul, and I have been doing this for over forty years. And little by little I discover something, I go a little further, I am more permeable.
Awase: practising with the same partner can help you harmonise with the other person.
Straight from the first part of the session, which is an individual practice, it is important to get into a certain state of mind. The harmonisation work continues in the second part, where we practise with a partner. To facilitate this, in our school we work with the same partner throughout the session. Of course, we could change for each technique, but if you want to harmonise, it is difficult to do so in just five or ten minutes with each person. For those who have been doing it for twenty or thirty years, this is fine… But if you are just starting out, say for the first ten years, it is also reassuring to stay with the same partner, so that you have time to harmonise and become imbued with the other person. Thus you can feel them, the first few contacts can sometimes be a bit difficult. But with the same technique, a second, then a third, you can go a little further, get closer to your centre, breathe the “fragance” of your partner better. Tsuda sensei used to talk about discovering the inner landscape of somebody, but it is more difficult to discover the inner landscape of seven or eight people in the same session. Sometimes, particularly at the end of a session, I ask people to change partners, especially during Free Movement. But of course we change every session – they are not partners for life!
The Non-Doing
Uke has a role to play, without being violent, they must be sincere in their attack because without this energy, Tori will be in the “Doing” and not in the “Non-Doing”. In aikido, I often see very gentle Ukes and Tori happily slaughtering their Uke. This is not my principle at all. When I talk about attack, I mean when Uke does a Shomen, a Yokomen, a Tsuki or a seizure, it is important that an energy comes out of it, he or she “does”. Tori, on the other hand, diverts it, lets the energy that expresses itself in the gripping of the wrist or the striking pass, he moves to the side and transforms it, then it is “Non-Doing”. Tori does not respond to the attack, they let that energy, that ki, flow, they go beyond the attack. Of course, Tori does not foolishly wait to be hit! Non-Doing does not mean doing nothing.
I also assume that when someone attacks another person, it is because they do not feel good about themselves… When you feel good about yourself, when you are alive, you have no desire to go and attack others. It would not even occur to you. It is because you do not feel good about yourself that this happens. We live in a violent world, and we have been brought up to react in line with this violence – we have to defend ourselves against this, against that… It has made us sick. By practising aikido, when you are Tori, you are “healing” this violence. This violence, which is in the other person, which is expressed by the role and firmness of Uke, one guides it to transform it into something positive and liberating.
Working with weapons: Ame-no-uki-hashi ken

Almost thirty years ago, I decided to use the term Ame-no-uki-hashi ken to refer to the work with weapons that we do in workshops and sometimes in regular practice. The ken, the sword, is a representation of the celestial floating bridge: Ame-no-uki-hashi. We speak of a celestial floating bridge when we see the katana with the cutting edge facing upwards, and we also speak of a celestial floating boat when the cutting edge is facing the other way, downwards. It is quite curious because it is both the bridge and the boat… It is what unites heaven and earth, the conscious and the unconscious, the Universe and us. When we work with weapons, they are an extension of ourselves, beyond our skin, something that allows us to go a little further, to discover our sphere too.
Ame-no-uki-hashi: being on the celestial floating bridge, this was an image used by Ueshiba O-sensei and passed on to us by Tsuda sensei. To be on the blade of the sword is to be in a state of attention that could even be described as “divine”, where a different perception can occur. I do not want to get into a discussion about whether or not weapons should be used in aikido, it does not matter. I work with weapons because it forces us to be in a state of extreme concentration while maintaining relaxation. They also help me to make the ki lines visible in a more obvious way, both those of my partner and those that come from myself. For example, when I place two bokken on my centre in a demonstration, I show that the strength comes from the hara and not just from the muscles.

Kokyū Hō: breathing
Traditionally with Tsuda sensei, the session always began with the Respiratory Practice, then we did the exercise he called Solfège4, then we worked on techniques and at the end there was always Kokyū Hō in suwari wasa.
For Tsuda sensei, Kokyū Hō was an opportunity to do just one thing: breathe. He gave us, among other things, the visualisation of opening the arms
as the lotus flower opens. There is no more technique, just a person grabbing you, and then you breathe through them, circulating the ki through your arms, through your partner. Whatever the partner’s resistance, we open up to it and achieve the fusion of sensitivity between ours and theirs.
For me, every Kokyū Hō is different, with every person. There is no particular technique, but there are lines that spread out from the hara, it is like a kind of sun that shines and you can follow each ray of sunlight to find that hara, something ignites and the person falls to the left, to the right and you do the immobilisation. For me, this is a special moment of deep breathing. When I talk about deep breathing, I am obviously talking about ki, meaning that when you breathe deeply the ki starts to circulate in a different way.
Awase beyond the tatami: taking care of the baby, the height of martial arts
‘Knowing how to treat babies well is for me the height of martial arts’ 5. When Tsuda sensei wrote this sentence, he was relating aikido to the way of looking after a baby in Noguchi Haruchika sensei’s Seitai. He also said that taking care of a baby is like having a sword over your head; as soon as you make a mistake, “snip” the sword falls.
If we draw a parallel with aikido, the baby is both much more demanding than the master and at the same time much more gentle; in Seitai, taking care of the baby means having constant attention, it means abandoning yourself. The greatest masters talk about the importance of abandoning yourself, it is central to martial arts. Awase, this fusion we talk about, is also accepting to abandon yourself. With a baby, it is all a question of sensation, we are in a constant fusion of sensitivity, like when a mother knows if her baby is crying because it has to pee or if it is hungry or tired. In the same way, but in reverse, for the samurai facing their adversary, the art was to discover in the other the moment when their breathing would become irregular, the moment when they would be able to strike. It means calling on all our abilities.
Taking care of a baby is discovering a world of sensitivity, for example through the art of giving a hot bath in Seitai. Knowing how to put a baby into the water when it breathes out and how to take it out of the water when it breathes in, when you are able to look after a baby in this way you are also in martial arts. Touching a baby, changing a baby in the rhythm of its breathing, putting a baby to sleep and laying it down without waking it up… Of course, it is much more flamboyant to pull out your katana and pretend to cut off a head! But for me, it is so much more difficult and important to put to bed a baby who has fallen asleep in your arms, to be able to take your hands out from under the baby without waking it up, that is art! With an aikido partner, you can “cheat”, you can use a little shoulder pressure, you can push… but with a baby, you cannot cheat. There is fusion or there is not. I learnt a lot from my babies, I think I learnt as much from them as I did from Tsuda sensei, although in a different way.
Musubi and awase: the beginning
It is generally believed that one must begin by learning the techniques and that after many years of work one can grasp awase and musubi. In our school, the Respiratory Practice and the fusion of sensitivity are at the beginning and inseparable from the rest. All our research is done through breath, “ki”. This direction allows us to deepen the research in simplicity rather than acquisition, and in this sense we meet Ueshiba O-sensei’s definition: ‘Aikido is Misogi’.

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 practise. 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…
