Be Skeptical, but Learn to Listen. - Don Miguel Ruiz

In order to protect our emotional wounds, and because of our fear of being hurt, humans create something very sophisticated in the mind: a big denial system. In that denial system we become the perfect liars. We lie so perfectly that we lie to ourselves and we even believe our own lies. We don’t notice we are lying, and sometimes even when we know we are lying, we justify the lie and excuse the lie to protect ourselves from the pain of our wounds. The denial system is like a wall of fog in front of our eyes that blinds us from seeing the truth. We wear a social mask because it’s too painful to see ourselves or to let others see us as we really are. And the denial system lets us pretend that everyone believes what we want them to believe about us. We put up these barriers for protection, to keep other people away,

We don’t see the truth because we are blind. What blinds us are all those false beliefs we have in our mind. We have the need to be right and to make others wrong. We trust what we believe, and our beliefs set us up for suffering.

You don't need to change the world; you need to change yourself.
