Whenever we go on a mission of cheating or lying does not matter how small it is…we always start building a justification inside that why am I doing this and we try to satisfy inner self as deep inside we know it, this is not the right thing to do. We build that justification and feel happy….if it is such a right thing why do you have to build a justification? What happens is, we always have an ideal self image and we would like to see ourself like that and whenever we do anything which goes against that image or the image starts getting distorted, not to feel bad, we build justification, so that our ideal self perception is intact. To save that, we start an odyssey of lying and deception. Before you are cheating someone else, you start cheating yourself as you are doing lots of degrading efforts to save that. You start cheating yourself as you will believe the lie that you are like that, however, truth is there is no such person in existence, the one which you are carrying as idealself is just in your thoughts. So before cheating someone else, you are cheating yourself. You better keep yourself intact instead of worrying about others or you will not find yourself.
