In this life we choose our friends and enemies of the next life. Both hate and love make us attracted to each other. Do we hate or love each other? That's what it's all about.
Know that you can never defeat an ‘enemy’ by force, for any violent overpowering is temporary. The real Human you can neither kill nor destroy. Therefore, learn to look behind the outer man. No relationship will then be more conflictual and war turns into peace.
