QUOTE : We are often unaware of the real causes of our feelings, choices and behavior. Conscious access to them is very difficult. It sounds to be amazing at first sight -- you are happy, but you do not know the real reasons for your happiness, or you hate deeply, but the real causes of your hatred are hidden in your unconscious mind. What you think about the real cause of something can only be an illusion unconsciously created by the brain. It can be said that the life of the absolute majority is more like an illusion for that reason.
