Susan Piver writes about meditation, fear and the other negative emotions:
I once ran into a friend and fellow practitioner as I was exiting a contentious business meeting. He could see that I was upset. (My sobbing must have given me away.) I explained what had happened at the meeting and then expressed dismay at the weakness of my Buddhist practice: “I must be a very poor practitioner if one jerk can throw me so completely into hysterics.” He said, “So you think that not getting upset is a sign of progress?” I realized that I had been hoping it was. “No,” he said. “Progress is how quickly you can stabilize your attention on what you’re feeling. Progress is how quickly you can come back.”

I too believe that if I just practice hard enough, long enough, I will stop feeling the negative emotions; I would be "purified". Each time I find myself angry, jealous, arrogant - I tell myself that I have not practiced hard enough. Or, that I have failed somehow.
I need to remember this.
