The human mind is like a mirror. If you polish it then everything looks
clear and beautiful. Everyone has a background, culture, language, education etc. that shapes their mind in some way or the other. A mind that is not polished reflects a person’s surroundings and can distort the image or make it ugly.
The human mind, when observing itself through introspection, looks like how an unpolished mirror would reflect. The mind is a tool. It can be used to help or harm oneself, society and nature. For example, it is not a good idea to be too critical of oneself. A mind that is constantly judging itself will suffer from low self-esteem and depression. People tend to be too critical of themselves and others which can lead to feelings of self-pity, guilt and anger. This is why people turn to drugs, alcohol or other addictions.
If you want to be happy, then it is important to be kinder and more positive towards yourself.
