Sri Sri Ravi Shankar: You got slapped twice by the same person or a different person? That makes all the difference!
You know, you can keep turning your cheek to different people and they will only slap once, that does not show you of your intelligence. Got it!
You should see whether the person who slaps you on one side, if he is sensitive and cultured then you can show the other cheek, no doubt. But if the same person is insensitive, then not the third time, because you have only two cheeks. Got it!
