Final answer:
The Taijitu, known as the yin-yang symbol, represents Daoism's principle of balance in nature, depicting the interdependent forces of yin and yang, and is emblematic of the Daoist belief in harmony with the natural way of the universe.
Step-by-step explanation:
The symbol that shows Daoism's stress on the importance of balance in nature is the Taijitu, commonly known as the yin-yang symbol. This emblem represents the fundamental Daoist concept that all aspects of life are composed of two opposite but complementary forces known as yin and yang. Yin is the dark swirl, symbolizing passivity, femininity, and darkness, while yang is the light swirl, representing activity, masculinity, and brightness. The Taijitu illustrates the balance and interdependence of these forces and emphasizes the Daoist belief in living in harmony with the natural way of the universe, or the dao. This philosophy encourages individuals to practice wu wei, or nonaction, which is an acceptance of the natural flow of life and a refrain from imposing one's will against the natural order.
