Yin and Yang

The concept of Yin and Yang is so basic to Tai Chi that instructors often forget to explain it. I think that part of the reason lies in how common it is to see the Yin Yang symbol these days. You just assume that everyone understands.

Big Bang Representation

In ancient Chinese thought the whole of existence is manifested through a repeating pattern of dynamic opposites. Two opposing polar forces that belong both together and separately. Wu Chi, the state before the division into these polar forces of Yin and Yang can be likened to whatever was before the Big Bang described by modern science. Yin is the name for relatively negative forces, Yang the relatively positive ones. Common examples of Yang energies are things like up, the sun, light, mountains, fast running water, a tall tree. By contrast common examples of Yin energies are things like down, the moon, dark, valleys, deep still water, a blade of bendy grass.

One can even see that Yin and Yang exists at a molecular and sub-molecular level. Any compound (e.g. water, carbon dioxide or oxygen) is a bonding of elements that hold because of a harmony of positive and negative forces (Yang and Yin energies) that emerge from a previous imbalance. Even within a single element, the atoms and their circling electrons bond together to create that piece of physical reality. So in Chinese thought reality exists because of a separation of Yin and Yang which on many different levels seeks harmony with a compatible opposite. However they can never achieve true harmony because they are all acting within the envelope of the Universe that is holding Yin and Yang apart. This original separation is the energy that fuels all that we are and all that we experience.

We are all aware of the most common depiction of Yin and Yang – the circle divided into two swirls. One is black and one is white, almost like two fishes swimming in circles. In addition the white (Yang) contains a spot of black and the black (Yin) contains a spot of white. This is a very clever representation of a multi-dimensional concept. The inventors of this symbol are trying to convey, not only the separation of Yin and Yang as discussed above, but also the constant interplay between the two forces that occurs when you add the dimension of time. If you start at the tail of Yin for example, you find that over time a force can become more and more yin. But when it is most Yin (at its fat head) you become aware of a spot of Yang and it you push further into Yin – bam! - it convert to being a Yang force. In my interpretation of this diagram I like to imagine that the spot is the tail of the next energy appearing like a whirlpool or black hole, that appears as you approach the heart of the current energy.

To reiterate, although we can see there is a separation of Yin and Yang, in essence there is also no separation, just interplay between two forces that must join and become one, yet cannot due to the greater force of, let us say, the Big Bang.

An understanding of these forces underpins all of ancient China's knowledge: from the philosophy of Taoism; to art, medicine, engineering and all manner of martial arts and strategy.

Within Tai Chi most people's work (whether they know it or not) goes into understanding two major Yin/Yang systems:

  1. The change and interplay of Yin and Yang energies in your own mind/body system

  2. The change and interplay of Yin and Yang across two merged mind/body systems (the opportunity to merge arises when you have contact with an opponent).

Tai Chi, Nick Cheang

In order to explain these I want to start by talking about how Tai Chi demands a physical understanding of Yin and Yang. Our bodies must stand in a state of balanced Yin and Yang so that we are always stable. We never throw our weight as is often done in the external martial approach, because from the point of throwing to the point of recovery we have no rooting, no stability and therefore cannot change. As a result a good practitioner can attack at any time and change their mind to do something else at any time. Once you have this ability you won't want to do anything that compromises it. In Yang style Tai Chi this ability to always balance Yin and Yang as we move about is learnt through slow large circle form practice. The constant weight shifting from one leg to the other combined with different types of waist turn and arm and leg movement gives you practical knowledge of how to stay centred from extremely compressed (overall Yin) to extremely stretched (overall Yang) postures. Small circle forms assume you have already experienced the extremes of Yin and Yang movement elsewhere.

Tai Chi movements physically balance Yin and Yang to create stability. Within that balance how stretched or compressed the movement is from our normal standing position is one of the factors that dictates whether the overall expression of the posture is labelled Yin or Yang. For example a common posture like an extended Ward Off is Yang, whereas something like the drawing, compressing action of Rollback is Yin.

From a stable posture the soft usage of muscle and intention focussed from the centre outward beyond the physical limits of the body leads to stronger and stronger energy flow and balanced projection of energy ('Chi'). Our Standing Post Chi Kung meditation teaches us how to project energy through intention from a fairly neutral posture. When we make the posture many times more Yin or Yang (e.g. an extreme Ward Off or Rollback) there is a many fold increase in the power of the projected energy.

Further the energy projection does not have to have anything to do with the overall nature of the physical posture. So from a Rollback position you can produce a very strong push that would seem Yang and from a Ward Off position you could create a drawing action that would seem Yin. This is how Tai Chi people become tricky and confusing to confront, bringing seemingly impossible power from unexpected positions.

Small Frame Tai Chi

Therefore, although the physical postures of Tai Chi are physically and mechanically strong the objective is not to use these to block and bash the opponent. Instead we train to use the energy projection through the postures to merge with an opponent, control them and defeat them. It is the understanding of energy flow that will ultimately show your level of Tai Chi and is the reason why people are attracted to learn the art for health and well-being in the first place.

Strong energy projection is what allows you to merge with and overcome a powerful opponent. In our school we test a posture such as An (or 'Push) by pushing on it with constant forward force. On contact the person being tested must therefore:

  • Begin by making sure they are themselves stable (i.e. have harmony of Yin and Yang within their posture).

  • Make themselves stable and relaxed even though someone is pushing on them. This creates harmony of Yin and Yang through both their own and their opponent's system.

  • Project energy to overcome the flow of energy coming from the tester and thereby blast them away.

Once you have played around like this for a while you begin to gain a much deeper appreciation of Yin and Yang in yourself and how it feels to encounter those states inside your opponent. For example, beyond the physical structure being Yin or Yang, an opponent may be very hard and stiff in their arms and shoulders (the energy is too Yang and therefore bungs itself up) or perhaps too floppy around the mid-riff (too Yin). At this point you are learning to interpret the energy of another being. If you encounter the stiff arms and shoulders you should feel that it is easy to project energy upwards to sever the stiff portion of their body from the rest and in this way easily uproot them. Or on feeling the mid-riff you should be able to detect its inherent emptiness and just turn your waist to project the sideways energy to sweep them effortlessly away.

So to summarise, evidence of the interplay of Yin and Yang in Tai Chi can be seen in weight shifting, sinking, rising, projecting or drawing energy or being too relaxed or tense (i.e. disjointed, blocked or uneven in internal energy flow). In addition it is also looked at through the lens of energy projection. Under these circumstances you can see Yin and Yang through two merged systems. The system that projects more strongly or attacks Yin-Yang imbalances in the opponent more effectively wins. So if you knew nothing of Yin and Yang before, I hope that you know something about it now. Until next time, take care.
