Today, under the upright anti-corruption, some cadres lament that they are uncomfortable and not free. In a certain sense, this kind of psychology is inseparable from their views on freedom. As Marx said, the code is the Bible of people's freedom. The reason is easy to understand, but in the subconscious and intuitive feelings, some people still regard freedom as unrestricted, unrestricted, or less restricted, and rarely restricted. The problem is that unrestricted freedom is necessarily distorted and unreal. It can only be left in imagination. Whoever really treats liberty so freely, without resentment, and who does not know awe, will eventually pay a heavy price. What does this text mainly explain? ['Self-discipline is the premise and guarantee, and freedom is the purpose and dependence.', 'Freedom built on the base of discipline is true freedom.', 'A man who is free and happy must be the one who fears the law.', 'Failure to abide by self-discipline can lead to both physical and mental discomfort.']
