To begin with, remember what is "Yin" and "Yang". It is believed that in China, the words "Yin" and "Yang" meant "shadowed" and "lit" mountain slopes.
The simplicity and, at the same time, the depth of this idea of Chinese philosophers are amazing. Firstly, the mountain is always a single unit consisting of both slopes. Secondly, the lighting of the mountain changes during the day, as the Earth rotates relative to the Sun. And that slope, which was first light, then becomes dark and vice versa. It turns out that all the opposites are parts of a single whole and interconnected, interact and interpenetrate.
Discovered in China several millennia ago, this principle was originally based on physical thinking. The one primordial matter gives rise to two opposite substances - "Yang" and "Yin", which are one and indivisible. "Yin" meant "northern, shadow", and "Yang" - "southern, sunny slope of the mountain." Later, "Yin" was perceived as negative, cold, dark, feminine, and "Yang" - as positive, bright, warm, and masculine.
The symbol of the creative unity of opposites in the Universe was depicted as a circle, an image of infinity, divided by a wavy line into two halves - dark and light. Two points symmetrically located inside the circle — light on a dark background and dark on a light — indicated that each of the two great forces of the Universe carries within itself a germ of the opposite origin.
