In our universe, no one is perfect. Everyone has flaws and mistakes in their own right. But if someone calls himself or herself perfect, it is his or her ego that drives him/her forward. You don't necessarily have to be perfect every time. It's good to be imperfect. But the main thing is to accept your mistakes and work on them for better improvement. And this is what is called self-cultivation. Revolutionary movement for your own self.

A man is afraid to face reality and hence he covered himself in the darkest room. This is not good at all. Because he is not perfect, he is trying to hide from reality. But the truth is you can't hide from reality, it will find a way to touch you from anywhere. You can't defeat and change nature and its policies. Because you are also a part of this nature. If you want to change nature, just change yourself. Update your perspective on it. And that's it.
