The concept of Yin and Yang
Chinese classical philosophy holds that all things are born of two opposites.
The two opposites mentioned here are yin and yang, which exist in all things.
The picture shows the famous Tai Chi symbol, in which the black represents yin and the white yang.
They are supplementary to each other, transform themselves into each other and depend on each other. The human body is also composed of yin and yang. When yin and yang are balanced, both the body and mind are in a good state; however, their imbalance can lead to illness.
The Concept of Yin and Yang in Tai Chi
To understand and effectively control the transition between yin and yang in the human body, it helps to understand the application of yin and yang in combat. The manipulation of yin and yang is embodied in every tai chi exercise; whether in form or in application.
Within tai chi, there is a clear distinction between the empty and the solid plus also the rise and the fall in every movement. In the Single Whip posture, the left hand in front is the open palm and belongs to yang, and the right hand in the rear is the hook and belongs to yin. When the weight is on the left leg, it is solid and belongs to yang; then the right leg is empty and belongs to yin. At the same time, every yin and yang element implies the tendency to transform itself into the opposite. This is why the play of yin and yang within Tai Chi changes constantly and continuously like flowing water.
Just as the Tai Chi symbol is round in shape, there are curves and circles in every tai chi form and application. Transition between yin and yang relies on harmonious co-existence and soft transformation. The curved movements conform best to the natural state of the structure of the human body, making it easy to transform and adjust the balance of yin and yang in a smooth and even manner.
There is Yin in Yang and Yang in Yin
Motion and stillness exist together. The movements of Tai Chi are relaxed and slow. They call for stillness in motion to achieve the relaxation of the mind and body. At the same time, while in a still posture, there must be motion in stillness so that the movements do not grind to a halt and the mind and energy flow does not stop. Motion and stillness are classed in the West as two opposites but the coexistence of motion and stillness is the embodiment of Tai Chi; "There is yin in yang, and yang in yin."
Hardness and softness are combined: if a posture is too hard, it is easy to break; if too soft, it is easy to damage. Tai Chi stresses softness to achieve hardness. So exists the integral whole, dependent yet interdependent; whether in advance or retreat, in rise or fall, or in closing or opening. When one part moves, all parts of the body move. This effectively helps to integrate movement in the human body and maintain the harmony between yin and yang.
