What is qi / ki?

I've just finished reading this book: "The Spark In The Machine" by Dr Daniel Keown. Its a fantastic book about the connections between the science of Acupuncture and the mysteries of Western medicine. Totally recommended!

As you might imagine, in the book he talks a great deal about qi (chi, or in Japanese, ki), and I'd like to tell you something of what he says.

It seems to me the concept of qi has always been problematic in the Western world because qi actually represents a number of different concepts in Western understanding. It's been variously translated as "energy", "vitality", or "life force" as they are the closest words or phases we have to encapsulate all that qi is. I think "energy" is the closest word, so let's have a look at what kinds of energy can be included in the concept of qi.

Electrical energy

I've written about bioelectricity before. Firstly we have the nerves. All the cells in the body naturally generate a slight imbalance between negatively charged potassium ions on the inside and the positively charged sodium ions on the outside. Neurons have a much larger imbalance than others, and when the body needs to send a message from one place to another, it uses neurons to create a cascade of electrical signals to carry these electrical pulses of information. These signals are not like current in a wire because the information sent is in the form of a pulse of polarity changes called an action potential. So we have the electrical pulses of energy that travel down these pathways of connected neurons that we call nerves.

Fascia is connective tissue in the body – it's like the plastic wrapping around everything, defining the edges. Muscle fibres are encased in fascia, and the whole muscle itself is again wrapped in fascia – together they're called myofascia. At the end of the muscles, the muscle fibres peter out leaving just the fascia, which comes together to form the tendon. Ligaments are also strong cords of fascia. The organs are wrapped in a layer of fascia, and there is fascia connecting the skin and the flesh underneath. Arteries and veins are walled by fascia, it forms the lens of your eye, and bones could also be seen as crystallised fascia. Amazing!

The collagen triple helix structure

Fascia is made of collagen, which is formed of a triple helix of protein molecules. These helices spontaneously wrap around each other to form a "microfibril" and these microfibrils are laid down by the body along lines of physical (mechanical) stress. Per weight it is as strong as steel! The collagen proteins form a semi-crystalline structure, meaning it conducts electricity. Actually, it not only conducts electricity but it can generate electricity through the piezoelectric effect – the ability to generate electrical currents through deformation and pressure.

So that means that any time fascia (which, remember, is located everywhere in the body) is stretched or moved, it will generate tiny electrical charges. This is nothing to do with our nervous system, but to do with movement and mechanical stress. There is speculation that collagen will conduct electricity much better down its length than across it, meaning the microstructure may have far more order and importance than we realised (for more info read "Anatomy Trains" by Tom Myers). Woven into the fabric of our body is an electrically conducting and generating lattice - amazing!

The contact surfaces between different fascial planes (for example, the fascial wrapping around a muscle and the fascial wrapping around the organ it's next to) offer routes of "least resistance" for the transmission of these electrical currents. These routes are thought to form the basis for the Chinese energy channels.

In the book, Daniel Keown calls all this electrical information "ElecQicity" – the electrical component of qi.

Chemical energy

We take in oxygen through our breathing, and that gets attached to haemoglobin in the lungs and transported around the body in the blood. We also take in food which gets broken down in our gut into a number of chemicals including glucose. Cell respiration is a series of reactions in which glucose is oxidised to form carbon dioxide. The energy released in this reaction is used to make ATP (adenosine triphosphate) and when ATP is broken down in the cell, the energy released is used for processes such as DNA replication and muscle contraction.

The blood also carries hormones, which are body-wide chemical signallers. This information is also a form of qi energy.

In the Chinese system, the Kidneys are associated with the psycho-emotional state of fear. Attached to the kidneys are the adrenal glands which produce adrenaline and cortisol (amongst a few other things). When we sense danger, the adrenals kick in and the resulting hormonal release signals the heart rate and blood pressure to increase, the air passages of the lungs to expand, dilate the pupils, etc. The result is we feel scared or fearful.

In the Chinese system the Liver is associated with anger (i.e. feeling "livid"). The liver is primary organ for breaking down histamine, and histamine is the hormone of irritation. Of its many functions, one is to make the body irritable to infections, and we all know its effects when we have an allergic reaction. If the liver isn't working properly, we get a build up of histamine, and since frustration is the precursor to anger, we can see how the liver and anger are connected.

The Chinese system sees the Spleen as being associated with worry and with dwelling on things and ruminating. One of the hormones that is widely seen as being responsible for maintaining mood balance is serotonin (the so-called "feel good" hormone), and there's a link between a lack of serotonin and depression. And of course, dwelling or ruminating on thoughts is part of how depression works. In the body, 90% of the serotonin floating around is found in the gut (with the rest of it being in the brain). Of the serotonin found in the blood, 99% of it is in the platelets (involved in making blood clots), and one of the main functions of the spleen is to store (and destroy old) platelets. So if the spleen isn't functioning well then our serotonin levels are adversely affected and we may end up ruminating on things and feeling worried or anxious.

"The spleen and pancreas are so closely linked that they could be considered one organ" so Daniel Keown says (p188). There's strong evidence that these two organs share a common evolutionary origin, blood supply, and fascial connections. He goes so far as to suggest we rename the two together the Spancreas! The pancreas has two functions – one to provide enzymes for digestion, and the other to produce the hormone insulin to regulate the metabolism of carbohydrates (sugars), fats and proteins. One of the most important hormones for regulating the release of insulin is... seratonin!

Mental energy Intention/will

What is intention and action if not a coordinated direction of energy towards achieving a particular result? I would hazard a guess that human intention has at some level shaped everything you can see around you now – it's a very powerful form of qi.

Interestingly, the kidneys are also associated with will-power in the Chinese system. Most dopamine in the body is made (and found) in the adrenal glands, and we know that dopamine is very associated with risk-taking, reward, will and drive.

When we set our mind to it, we can coordinate all our various resources and direct them to great effect. Researcher Dan Siegel defines the mind as: "an embodied and relational process that regulates the flow of energy and information." But we have to remember the mind isn't the brain. In the Chinese system the brain plays a minor role in the whole system, being described in some sources as a "special form of bone marrow"! Actually, the point where the brain ends and the body begins is not easily definable. The brain, spinal cord and peripheral nerves are like one, but these peripheral nerves also blend with the organs. And whilst the nerves tell the organs what to do, the organs produce hormones that equally affect the nerves.
 
The mind is truly "an embodied and relational process" – it's in the body and it's all about relationships and connections. 

Organisational energy

The last form of qi I wanted to discuss I'm going to call organisational qi. It's the energy arising from evolution – how the body organises itself to form and grow as an embryo to baby; and how the body later organises repairs and fights of diseases.

Keown talks about this at length in the "Spark In The Machine" book. Some parts of the body are more complex than others, so you could say concentrations of organisational qi exist in different places. For example in the face there are many contours, sensitive muscles, and the eyes. The fingers and toes too represent transition points. It's no coincidence that all these areas are connected with the beginning or ends of the energy channels. When we injure ourselves, then a concentration of qi forms around the injury in the form of white blood cells and other repair cells.

One of Keown's definitions of qi is "intelligent metabolism" – an organised and directed movement of many forms of energy throughout the body.

Yoga to work with the seasons

How are you affected by the changing seasons? Do you just feel hot in summer and cold in winter, or do you feel some other effects of the seasons?

On Saturday (29/3) I went to a yoga teachers workshop run by my Zen teacher, Daizan Skinner, on the topic of the seasons – exploring the needs of the human system through the changing year, and how we can adapt our yoga practice to work best with each season.

Living in harmony with nature includes bringing body and mind into harmony with the changing seasons. I'm sure this was obvious to people in the past whose lives were much more connected to the outside environment, but these days, with our new fangled electric lights and central heating, we can live like there's no difference between winter and summer!

In the Indian yoga tradition, less emphasis is put on the seasons since India mostly has a sub-tropical climate. In the Ayurvedic system there are only three seasons: autumn/winter, spring and summer, whereas in the Chinese/Japanese system there are five (as we'll see below).

As I've written before, in the Chinese energy meridian system, each organ and organ meridian (see this page for simple meridian diagrams) is associated with a different quality, and the seasons are no exception. Each season is associated with two paired organs, and the properties of each organ and the effects of opening their meridian line dictates the flavour of your yoga practice for that season.

Here is a summary of what we learnt for each season.

Spring
Associated organs: liver and gall bladder

The liver is located on the right side of your body just under your rib cage, and the gall bladder is tucked in right next to it. The liver's function is to remove toxins from the blood, and the meridian line runs from the big toe up the inside of the leg up to the side of the belly.

The gall bladder stores and secretes bile to aid in digesting fats and acids, and its meridian line runs from the little toe right up the side of the body up to the head.

Any imbalance in the liver-gall bladder system tends to show up in the eyes, and/or as ligament/soft tissue tension or stiffness. When it's impaired the associated emotion is anger (we English have the term "a liverish person", or to be "livid"), and when functioning well we feel creative and kind.

So in the spring, our yoga practice should concentrate on working with stiffness in body (waking up from the winter) and stiffness in our attitudes, to help us detox, release anger, working with the eyes, and encouraging creativity and kindness. Postures should concentrate on stretching/opening the sides of the body and the insides of the legs.

Summer
Associated organs: heart and small intestine

As we all know, the heart pumps blood around the body. It is seen as the home of the spirit, and governs joy. Interestingly, the tongue has a special relationship with the heart, being thought to be an a kind of "offshoot", and our facial complexion often reflects the state of our heart. The heart meridian line runs down the inside of our arm into the little finger.

The small intestine is five metre long narrow tube in your belly that does about 90% of the work of digestion, absorbing nutrients from the food as it passes through. It's meridian line runs from your little finger back up the outside of your arm, zig-zagging across your shoulder, and finishing on the side of your face.

When the heart-small intestine system is impaired we feel arrogance and hastiness, whereas when it's functioning well we feel love and connection.

Yoga for the summer should concentrate on opening the chest/heart area, and make use of flowing postures with an emphasis on that quality of timelessness in order to counter any hastiness. This would be the time to explore a more athletic practice to get the heart rate going, and at the same time foster an appreciation and love of the body and mind. Bear in mind though, that in the summer the mind is at it's most outward looking and distracted, so balancing this with some time for quiet introspection and calmness would work well.


Late summer (harvest)
Associated organs: spleen and stomach

In our western medical understanding, the spleen is part of your lymphatic system, and acts as a blood filter, destroys old red blood cells and helps fight infections. In the traditional Chinese medical system though, it's understood to have a very different function! It's seen as governing the transportation and absorption of food and water, turning digested food into usable nutrients, and ki (chi) energy for the body. It's also understood to control muscle strength, thinking and pondering, and is connected to the lips and mouth (like the heart is to the tongue). The spleen meridian runs from the big toe up the front inside of the leg, over the front of the hip up to the arm pit.

The stomach is located next to the spleen, on the left just under the rib cage. It's function is to receive food from the oesophagus, and secrete acid and enzymes to digest the food. The stomach muscles contract periodically, churning everything around to help everything digest fully. It then passes this partly-digested food onwards to the small intestine for further digestion and absorption. The stomach line runs from the 2nd toe up the front of the leg, front of the hip, the front side of the belly and chest, finishing up on the cheek next to the nose.


When the stomach-spleen system isn't working too well then we feel worried and insecure; or if it's functioning well then we feel empathetic, and nourished.


Yoga for the late summer should emphasise our connection to the earth, perhaps with poses close to the floor. Smooth continuous movements help to extend and challenge the muscles, particularly along the front side of the body where both these meridians run. Obviously back bends work well for this, but beware that going into a backbend too strongly can stimulate worry and insecurity in some people, not release it. Exercises using the voice and explanations that encourage a very detailed attention to bodily sensations helps to assuage any pondering and worry.


Autumn
Associated organs: lungs and large intestine


The lungs obviously get us breathing – they control respiration. However, in the Chinese system, they are also associated with governing ki (chi energy), disseminating and regulating water in the body, and controlling skin and body hair. They are also connected to the nose. The lung meridian runs from the thumb along the inside of the arm to the shoulder.

The large intestine's job is to remove water and any remaining absorbable nutrients from the food as it passes through, before sending the indigestible matter to the rectum. As a matter of interest, the full digestion of our food takes about 16 hours from start to finish! The large intestine also absorbs vitamins that are created by the colonic bacteria, such as vitamin K, vitamin B12, thiamine and riboflavin. It's meridian line runs from the index finger along the top of the arm up, over the top of the shoulder, up the side of the face to the nostril.


When these organs and their energy systems are functioning well we have an ability to let go and move forward; when they're not there's a sense of grief or depression. There's a clear connection here between these emotional qualities and the organ functions!

Yoga for the autumn should therefore focus on releasing and letting go on all levels. Shaking movements very helpful for this. Since the lungs are involved, a focus on breath-work would also be good.


Winter
Associated organs: kidney and bladder

Physiologically, the kidneys act like a filters to remove wastes and fluids from the blood – each day they process around 200 litres, removing about 1-2 litres as urine. The kidneys make three important hormones: erythropoietin to stimulate the production of red blood cells, renin which is involved in the control of blood pressure, and vitamin D which controls calcium uptake and helps make strong bones. They are connected with the ears, and energetically, thought to govern the reception of qi (chi) from the air. They kidneys suffer a lot when they get cold, so in Japan, they often wear a 'haramaki' – a garment worn around the abdomen (hara) to keep the stomach and kidneys warm. In the days of the samurai, it was a long piece of cloth (often augmented with chain mail or other metals) wrapped around and around the belly, but these days you can get something far more comfortable and convenient. The kidney meridian runs from the ball of your foot, up the inside of your leg, and up the front of your belly and chest, finishing at your collar bone.

The bladder the waste fluids filtered out by the kidneys, meaning that we don't have to constantly leak waste fluids – we can go to the loo and release a batch at a time... It's normal capacity is 400-600 ml. The bladder is lined by layers of muscle tissue. During urination, the bladder muscles contract, and two valves open to allow urine to flow out to the urethra (which passes through the centre of the penis in men). The bladder meridian runs from the little toe, up the back of the leg, splits and runs in two parallel lines just to the side of your spine, over the back of the head and finishes in the corner of your eye.

When this paired system is functioning well we feel a sense of courage, or a can-do attitude; when it isn't we might feel emotions relating to despair. When the kidneys are feeling down, the whole system can feel down, so that's why it's so important to protect and take care of your kidneys.

Yoga for the winter should therefore focus on warming the body (particularly the lower back and kidney area; perhaps through tapping or rubbing), and opening through the kidney and bladder meridians. The feet can also suffer a lot at this time of year, getting cold and never seeing the light of day, so giving them some attention can be nice. Mobilising the joints can help to release trapped cold, and a slower, more restorative practice connects in with our winter hibernating tendencies.

Kidney tapping/rubbing

In the workshop, we then split into pairs, each taking a season and coming up with a 30min yoga sequence relevant to that season. Teaching these sequences back-to-back, we experienced a whole year of yoga in just 2 and 1/2 hrs!

Workshop on the 8 Silk Brocades of Qigong

On Saturday I went to a workshop at the ZenYoga studio led by long-time martial arts practitioner and teacher Keith Alker on the 8 silk brocades of Qigong (Chinese: Ba Duan Jin, Japanese: Hachi Danken). It was great - we learned just 8 very simple moves in 6 hours! Simple on the outside maybe, but certainly not simple on the inside... 

So what is Qigong? Qi (sometimes spelled 'chi', Jap: ki) is the universal energy, life force, or vital energy. Literally translated it means breath or air. Qi is the central underlying principle in traditional Chinese medicine, martial arts including T'ai Chi, and is also part of Zen practice. The idea is we're born with a certain amount in us, and then we take in more via food/air and directly from the universe, and use it to move and live. 

Qi flows around the body through meridians or energy channels. There are 12 main meridians associated with each of the different organs (heart, lungs, kidneys, etc), and 8 subsidiary meridians which include the belt meridian around your waist and the governing/conception meridian going up the spine, over the head, and down the front. 

Acupuncture/acupressure or any kind of Anma practice works on energising or unblocking these meridian lines and the points along them. A few of the most important points that Keith mentioned include Bai Hui on the crown of the head, Hui Yin on the pelvic floor, Lao Gong on the palm, Yong Quan on the sole of the foot, Ming Men on the small of the back, and the three Dan Tien's (energy centres) in the belly, chest and head. 

What is the difference between Qigong and T'ai Chi?  

Tai Chi is a Taoist moving meditation practice based on the interplay of the two complimentary forces - yin and yang. Tai Chi consists of four types of practice (the 'Four Pillars'): Qigong, Form, Pushing Hands and Application. When you see people practicing in the park they're most likely doing the Form. This is an aesthetically beautiful flowing sequence of movements designed to develop physical and mental skill and health, and varies in emphasis and complexity between different schools. Qigong (the first pillar) is the foundation of Tai Chi, and comprises a set of exercises to get your qi moving: both around and into/out of the body. 

Does the 'qi' or 'chi' in the two names refer to the same thing? It's pronounced the same...

I didn't know this before asking Keith, and apparently no it doesn't. The confusion arises from the different ways of romanising certain Chinese symbols. T'ai chi is the spelling using the Wade-Giles system and is the one most commonly known, whereas Taiji is the spelling according to the Pinyin system. The 'qi' in qigong refers to the energy that moves along the meridians, whereas the 'chi' in Tai Chi doesn't (hence Taiji is a better spelling). Taiji means the "great pole", or the "Supreme Ultimate".

At the beginning of the workshop Keith introuduced us to a few main concepts or principles.

One of these was that in all martial arts, qigong and meditation, we aim to regulate (1) the body – through alignment, movements, and the balance between tension and relaxation; (2) the breath (and hence our qi) – through breathing exercises, focusing on the tanden, breath sounds, etc.; and (3) the mind – through concentration, mindfulness, awareness, etc. 

He also talked about how finding the balance between yang/yin is so important. Taking our arm as an example, he showed how if you tense your arm, both the bicep and the tricep are working as if almost fighting each other. He called this double yang, and, he said, corresponds mentally to a state of active distraction. The opposite is a weak and limp arm which is obviously double yin, and corresponds to a kind of mental fog. Finding that balance (tension only where needed) is the key to correct practice in any of these arts. 

He also emphasised the concept of 'peng', meaning expansion – through the head, feet, hands, and ultimately through the energy body as well. It's very difficult to describe, but incredible to experience in a well practised teacher like Keith. It was literally explosive, and when he sent it in my direction I actually felt a physical push backwards!

So, what about the movements, the 8 silk brocades? Keith taught us the standard issue version from the Chinese Health Qigong Association and recommended by the Chinese government to maintain health and wellbeing after much research. 

The 8 exercises are:

• Holding the hands high with palms up to regulate the internal organs
• Posing as an archer shooting both left and right handed
• Holding one arm aloft to regulate the functions of the spleen and stomach
• Looking back to prevent sickness and strain
• Swinging the head and lowering the body to relieve stress
• Moving both hands down the back and legs and touching the feet to strengthen the kidneys
• Thrusting fists and making the eyes glare to enhance strength
• Raising and lowering the heels to cure diseases 

Now I need to go and practice them...  

Watch the full set of movements:

The Energetic Basis of Zen Yoga

This week I'd like to review a workshop I went to last weekend (12th Oct) led by our Zen master, Daizan on "The Energetic Basis of Zen Yoga". The workshop was designed to look a little below the surface of our Zen yoga and meditation practice - to look, as it were, at the underlying operating system, what the practice is built on.

This workshop formed part of the continuing professional development (CPD) days Daizan runs for his yoga and meditation teachers.

We started off looking at the Japanese word for yoga: do-in - literally translated as guiding and pulling! Sounds strange until you think of it in terms of energy. We guide and direct our energy around the body using movements and stretches in order to unblock or work on certain channels. That really set the scene for what this day was about. (For the energy sceptics out there, see this article.)

The workshop was centred around the teachings of the first monk to bring Zen to Japan, Myōan Eisai (b. 1141). After originally studying Tendai Buddhism, he spent 4 years in China learning Zen (or Chan), before coming back to Japan and establishing the first zen temple in remote Kyūshū (the third largest island of Japan to the southwest). Among his notable disciples was Dōgen, founder of the famous Sōtō Zen school. Eisai is also credited as the first person to bring green tea into Japan from China.

It seemed Eisai was pretty successful (read politically skilled) at bringing Zen into the Japanese mainstream, and in 1202 he founded the famous Kennin-ji temple in Kyoto (still very beautiful and worth a visit today). The Shogun (military governor) at this time, Minmoto no Sanetomo, was a complete alcoholic, and Eisai took on the responsibility of trying to get him to sober up an live a more healthy life. Eisai thought that he could get him to drink tea instead of alcohol... Jolly good plan I say ;-)

Drink Tea and Prolong Life

In the process of trying to convince the shogun it's not all about going out on continuous benders, and that being an alcoholic is actually very bad for the body, he wrote in 1211 a book called the Kissayojoki - literally translated as "Drink Tea and Prolong Life". In it he says "tea is the most wonderful medicine for nourishing one’s health; it is the secret of long life." More on that later.

As you might imagine, it actually contained more than just a plea to drink tea. It was a manual for healthy living, in fact describing very much what we would call Zen yoga. The Kissayojoki is part of the tradition of Yangsheng (Chinese) or Yojo (Japanese) referring to a broad array of practices aimed at nourishing and prolonging life through breathing exercises, dietetics (especially abstention from grains), sexual practices, meditation and visualization exercises, pharmaceutical prescriptions, and methods of "guiding and pulling" (Japanese: Do-in, Chinese: Dao yin). Why you'd want to prolong your life will be the subject of a future article.

One of the central ideas that's been around in traditional Chinese medicine for at least 4000 years is that of the energy meridians. These are energy pathways through the body that make up a circuit or web that delivers our life force, (Chinese: qi, Jap.: ki) to the organs and tissues of the body. There are 12 major meridian channels, each correlating to the organs in the body in a reciprocal relationship. For example a healthy liver allows energy to flow easily along the liver meridian, and unblocking the liver meridian can help the liver function better. The idea is that when meridians are blocked, or the flow is too great or too little, problems result.

Qi/ki is stored in three main centres in the body, known as Tan Tien (or Dan Tian; Chinese) or Tanden (Japanese) literally translated as 'field of elixir'. They are the East Asian equivalent to the Indian Chakras. The main tanden is in your belly, known in Japanese as your hara.

Japanese monks have been involved in accupuncture at least from 1227, which implies a good understanding of the energy meridians (Japanese: myaku). In the Kissayojoki, Eisai goes into some detail about the meridians and their relationship with the organs (see picture).

So why tea?

In the meridian system, each organ and organ meridian is associated with a different quality - season, colour, taste, element, direction, emotion. Here are the organ associations for the 5 tastes:

Heart – Bitter
Liver – Sour
Spleen – Sweet
Lung – Spicy
Kidney – Salty

The heart is seen as being the chief among the organs, but the problem was that at that time (and probably still nowadays) very few bitter foods were eaten - particularly by this drunken shogun. Nowadays those that are bitter, we tend to liberally sweeten.

So, as a way of balancing our diet and restoring health to our chief organ, the heart, Eisai suggested drinking tea. If you've ever had green tea, you'll know how bitter it is! These days other bitter foods include coffee, beer (bitter), cocoa/dark chocolate, olives, and citrus peel.

Prolonging life further

Of course, balancing the diet and promoting the health of our inner community of organs is just the start. We can't do anything if our physical body is out of whack, undernourished, weak, unbalanced. Once we've got that under control though, we can start working on boosting our health and wellbeing higher and higher - and this is how we really prolong our lives.

With this in mind, the physical yoga practice during the workshop focussed on stretching and opening up all our main meridians. Not only is it important to open/unblock these channels, but it's also important to get the energy flowing down them, and for that we did some practices using the sound 'mu'.

Mindfulness and meditation are also an essential part of this unblocking process. If you're interested I run regular courses in mindfulness in Camberwell, London.
