“ The MistakeWith the mistake your life goes in reverse.Now you can see exactly what you didWrong yesterday and wrong the day beforeAnd each mistake leads back to something worseAnd every nuance of your hypocrisyTowards yourself, and every excuseStands solidly on the perspective linesAnd there is perfect visibility.What an enlightenment.
