Its meaning is briefly explained as follows:
Wu Ge, is to ask people to experience their own things, personally handle their own things, that is, to materialism, to increase knowledge. Read for knowledge, practice for knowledge, then distinguish things clearly and do your best.
To know is to seek true knowledge. Find out your inner knowledge from the theory of deducing things. Just like a mirror, everything was originally bright, but it was obscured and dim by things. Now it gradually wipes away the dust, restores the light and has true knowledge. The so-called knowledge refers to moral consciousness. When you know it, you can distinguish right from wrong, good from evil, and you can see it in your heart. When you are satisfied, you will know what you are.
Sincerity means honesty in the mind. If you know enough, you can get real meaning, which comes from your inner nature. You can naturally not deceive others or yourself. You should work hard on "being cautious and independent", be strict with yourself, cultivate self-cultivation, and integrate knowledge with practice.
Righteousness is to get rid of all kinds of uneasy emotions, not to be shrouded in material desires, and to maintain peace of mind. If you don't deceive yourself, then the noumenon of the heart, things can't be moved, and everything is right. If you get the right result, you will be fair, honest and clear, without any emotion or prejudice. Deliberately sincere and then righteous words.
Self-cultivation means constantly improving one's moral cultivation. Only when one's moral character is correct, impartial and free from evil thoughts can one win the support of the people. Self-cultivation is not only the foothold of respecting things, knowing and doing, sincerity and integrity, but also the starting point of housekeeping, governing the country and leveling the world. The mind is right and then the body is repaired, and the body is repaired and then the family is neat.
Taking care of your family is to tidy up your family. Only by educating your family well can you educate the people well.
Governing the country means governing the country by virtue, governing the country by virtue and governing the country by benevolence. You mainly protect the people like a newborn child, educate the people with the best virtues, and make them go to the old and welcome the new. Rulers should let the wind of benevolence, respect, filial piety, kindness and faith flood the whole country, so that the country will be governed and the world will be peaceful.
To level the world is to spread benevolent policies to the world and make it peaceful. A peaceful world, the most important thing is to ask the monarch to have a "clean way", that is, to measure the noble and lofty qualities of the people with self-care and set an example for the people. Because there are many ways to level the world, this requires the monarch to respect the elderly, respect Changxing, care for the lonely and love the people, and conduct benevolent policies. You mainly practice forgiveness (don't do to others what you don't want others to do to you), be honest and upright, put morality first, advocate good officials, advocate loyalty, broaden sources and reduce expenditure, and be both righteous and beneficial, so that the world can be peaceful.
