How Can Hatred Be Overcome?

The master and student joined each other by the stream for their daily wisdom talk.
The student asked the master, "Honorable One how can hatred be overcome?"
The master took out his walking stick and smacked the student hard on his shoulder.
The student became enraged and at first felt as if he wanted to strike his master. The student then thought, here I have given all my time and effort to the spiritual life and the master treats me like a dog. His anger changed to hatred for his master. 
The master sat quietly.
The student began to settle down and the student's feelings of rage began to subside. 
Then the master lovingly smiled.
The student loved the master's smile. That smile always made him feel good. Then the student noticed that just a few moments ago he was full of anger and even had hatred for his teacher. But now he felt the love and respect for his master that he had always had.
The student now understood how to overcome hatred.
