Based on classical Chinese philosophy and foundational in Chinese Traditional Medicine, the Yin Yang theory has evolved into an interesting concept that has many applications today. Usually the term is used to denote oppositely polar or opposite forces in nature, and the principle itself is that all things, characteristics or processes exist as inseparable and contradictory opposites, for example, woman-man, day-night, cold-heat.
Opposite Yin Yang characteristics:
|black color||White color|
|even numbers (e.g. 6)||odd numbers (e.g. 9)|
|peak of influence at winter solstice||peak of influence at the summer solstice|
If you look deeper into the concept of Yin Yang, you can understand that not only closely related characteristics, but also having a significant influence on each other, apply to it. The two opposites Yin and Yang attract and complement each other, and, as their symbol shows, each side is based on an element of the other (represented by an interspersed color of the opposite color). Neither pole is superior to the other, and since an increase in one leads to a corresponding decrease in the other, it is necessary to achieve the right balance between the two poles in order to achieve harmony.
The earliest similarity to the Yin Yang symbol was found on the remains of various animals used in China for fortune telling and served as a simple indicator of natural phenomena (Yin symbolized night or the absence of sunlight; Yang represented day, or the absence of darkness). These oracle bones have been used since at least the 14th century BC. However, the earliest evidence of the Yin Yang symbol that has come down to us as we know it dates back to the 3rd century BC.
Following symbolism, the Yin Yang philosophy first appeared during the Han Dynasty and actually came into use during the Zhou Dynasty, when Yin Yang began to be associated with the concept of Qi - life energies. In fact, Yin Yang came to represent the complex duality of life and the overriding need for balance and moderation. This metaphysical worldview was used not only by Chinese philosophers such as Confucius and Lao Tzu to form their own religious and philosophical teachings, but also by Buddhists, Vedantists, yogis and doctors of traditional Chinese medicine.
And despite the increasing number of meanings and concepts created over time, the Yin Yang symbol rightfully remains fundamental and comprehensive.
