Master of emotions, not their slave

One day Buddha passes through a small village where some people throw filthy languages at Him.

Buddha listens to them quietly for a while and said: " thank you, but I have to hurry to another village."

One guy just can't believe what Buddha said and asked: " don't you hear we are swearing at you?"

Buddha replies: " I won't be commanded by what people say nor react to people's emotions. I am the master of emotions, not their slave."
