It is often said that a person should have morality. But why should there be morality? What is morality? Most people want to be a moral person, in order to get recognition and respect from others. The life of these people is miserable, because they live purely for the recognition of others. Therefore, having morality becomes a kind of helplessness in life that they don't want to do it, can't do it well, but have to do it and have to do it well. Their lives have become living for morality, and they themselves have become slaves to morality. For a wise man whose human nature has been liberated, morality is only a tool, a measure and a countermeasure for him to create happiness for himself, others and society and enjoy the happiness of life. They never live for morality, but let morality be designed to achieve his purpose in life. What is morality? The original intention of morality refers to people's attitudes, processes, methods and behavior patterns in their life practice. Tao is an analysis of the objective factual conditions that people face in order to create their own human happiness, freedom and enjoy a happy life. Morality is the choice of people's attitude, way and behavior mode based on the analysis of objective reality. That is, people's attitudes, ways or behavior patterns in communicating with others in life practice. In the word morality, Tao is the core, virtue is the form, Tao is the cause and virtue is the result. Tao is the source, and virtue is the flow. Tao is the foundation, and virtue is the purpose. Tao is skin, and virtue is hair. Tao is a tiger, and virtue is the skin of this tiger. What modern people call morality has long deviated from the essence of morality. Most of its contents only have virtue, but no Tao. Therefore, it is a morality that does not talk about Tao, a morality that does not talk about the root but only seeks the end, a morality that only seeks the form but not the content, a morality that only seeks the result but not the cause, and a morality that only talks about the flow but not the source. What people usually call morality is simply imitating the attitudes and behavior patterns of predecessors or others.
