Get rid of negative karma?

Question - Gurudev, how does one get rid of negative karma? 

Gurudev Sri Sri - I want to ask you a question. When the lights were not switched on in the room, there was darkness here, right? When the lights came on, where did the darkness go? Did it go to the other room? Did the darkness escape through the window? In the same way, if negative karma is there, see it as little darkness; there is no light there. Flip the light on and darkness vanishes. How to get rid of negative karma? By meditation, service and knowledge. Serve the needy. Know that it (the negative karma) does not touch you, even shadow cannot touch you.
