According to Chinese tradition, Lao Dze lived during the period of Kung Fu Dze in the 6th century BC, in the state of Chu, one of the seven major countries that were part of China, before being united by Qin emperor hundreds of years later.
Legend has it that Lao Dze and Kung Fu Dze met each other, and after Chu emperor decision to choose Kung Fu Dze to write the constitution of the state, Lao Dze decided to leave for the Himalayas.
Confuianism, Taoism, and Buddhism
After Emperor Chu heard that Lao Dze had left, he sent emissaries to the border guards to announce that they would arrest him and force him to write his teachings. One of the guards saw him coming up on his Buffalo toward the border. He stopped him and asked him to write his teachings. Lao Dze sat there writing The Book which called Dao De Jing (The Way) and then continued on to Himalaya.
The Dao is a rather mysterious worldview, because of its lack of pretension to say very clear things. The first song that opens the Dao (only the Bible has been translated into more languages) speaks of the Dao and the lack of definition of the term. The Chinese Dao is a "way," but not a way in the banal sense of a road.
The Dao can be the way things happen, it can be the power behind things, it can also be God or kind of God. The Dao is also the way in which all things work together and are interconnected, for example, the bee and the flower. What is the differentiation between them? After all, the bee is nourished by the nectar and fertilizes the plant.
Dao, in Chinese
Our connection to Dao is through the loss of our prior knowledge, that is, by the loss of the fixations we have about things, decisions based on our education, and our early assumptions.
The less we know, the more we strip ourselves of those fixed perceptions, the more we can connect to the true nature of things. Understand how they work. Our preliminary knowledge prevents us from seeing and understanding the Dao.
Daoism as a method advocates a principle called Wu Wei, meaning immobility. Our ability to be in harmony with the Dao, to connect to it, is by reducing redundant movements, similarly to reducing unnecessary knowledge.
For example: Suppose someone is attacking you and you defended yourself in motion; this is a necessary movement. But suppose he failed, and now you are chasing him and trying to attack him, this is an unnecessary movement.
Another well-known principle is Yin & Yang, that is, a cyclicality that occurs all the time between opposing energies in nature.
Yin and Yang
Yang is masculine, quick, warm, the Yin is feminine, cold, slow. These energies exist in constant contrast; they are mixed with each other and replace each other, for example, day and night, light and darkness, cold and heat. The Dow served as a basis for Chinese medicine, Tai Chi, and Kung Fu (later, after the interaction with Buddhism gave birth to Zen Buddhism)
