The Taijitu, also known as the Yin-Yang symbol, holds great significance in the School of Yin-Yang. This symbol represents the fundamental principles of balance and harmony in the universe, as well as the interdependence and interconnectedness of all things.

In the School of Yin-Yang, the Taijitu is seen as a visual representation of the concept of Yin-Yang, which is the foundation of the school's cosmological and metaphysical synthesis. Yin and Yang are two opposing forces that are constantly in flux, yet they are also complementary and necessary for each other's existence. This concept is reflected in the circular shape of the Taijitu, with the black and white halves blending into each other.

The black half, known as Yin, represents the feminine, passive, and receptive aspects of the universe. It is associated with qualities such as darkness, coldness, and stillness. On the other hand, the white half, known as Yang, represents the masculine, active, and assertive aspects of the universe. It is associated with qualities such as light, warmth, and movement.

The two dots within each half of the Taijitu symbolize the presence of Yin within Yang and Yang within Yin. This signifies the idea that even in the most extreme states, there is always a trace of its opposite. For example, in the depths of darkness, there is always a glimmer of light, and in the peak of activity, there is always a moment of stillness.

The circular shape of the Taijitu also represents the cyclical nature of the universe, where everything is constantly changing and evolving. This is reflected in the concept of the Five Elements, which are represented by the five different colors within the Taijitu. These elements (Wood, Fire, Earth, Metal, and Water) are in a constant cycle of creation and destruction, and they are all interconnected and dependent on each other.

In the School of Yin-Yang, the Taijitu symbol serves as a reminder to seek balance and harmony in all aspects of life. It teaches us to embrace the duality and interconnectedness of all things and to find unity within diversity. By understanding and applying the principles of Yin-Yang, one can achieve a deeper understanding of the universe and their place within it.
