Most of us tell lies or play games. Seeing this is a step on the way to a more peaceful life. Fear and ego are two sides of the same coin. They exist because your body desires to live forever. Evolution has programmed it this way.
Fear can affect the toughest of people.
For example, a soldier who has experienced battle might be afraid of public speaking. Violence and other extreme control patterns often spring from an attempt to cover up an inner fear, if only of loss of face. When criticised, we feel a need to justify ourselves. This sets off reflections. It is hard for the ego to take criticism without reacting.
