We must look upon our knowledge of others who have hurt us as a special kind of doorway, and not as a potential psychological weapon. To use it as a doorway means that we can learn how to walk past the parts of us that want to punish others for their act of ignorance against us. And we are helped to make this more compassionate choice by our remembrance that the first person to be injured by any dark design acted against another is the one who carries it out.
