The mirror says that whatever it views it accepts that as true. Whatever it sees it reflects that without any distortion. Generally, the people are affected by love or dislike. People don't reveal the truth many a time and speak after being affected by love or hatred. The mirror is not affected by emotions. It does not promote illusions. The illusions take a person far form the world of reality. It conveys the message that we should face and accept reality without indulging in self-pity. The mirror has no pre-thoughts, it means that it reflects everything accurately, objectively and in a dispassionate way. It is not affected by the fears, anxieties, irritation of the human beings who look into it. The mirror does not judge others by any pre-conceived notions.
