Firstly, "Tao" is the origin of all things in the universe. Everything in the world, from mountains, rivers to birds, flowers, fish and insects, is born from "Tao". As Laozi said, "Tao gives birth to one, one gives birth to two, two gives birth to three, and three gives birth to all things." It exists before heaven and earth and is the starting point of everything.
Secondly, "Tao" represents the laws of nature. The alternation of the four seasons, the change of day and night, and the operation and development of all things follow the laws contained in "Tao". If people want to live a smooth life, they need to conform to this natural "Tao" and should not go against nature.
Moreover, "Tao" is also a spiritual realm and a principle for dealing with the world. It advocates that people should copyright qualities such as modesty, non-action, and gentleness, and should not deliberately strive for superiority or interfere with the outside world excessively. People should face all kinds of things in life with a peaceful and natural attitude, so as to achieve the harmonious unity of the inner heart and the outside world. Understanding the true meaning of "Tao" can help us live and practice better.
