Suppose you are in the desert, and you only have one glass of muddy water. You have to transform the muddy water into clear water to drink, you cannot just throw it away. So you let it settle for a while, and clear water will appear. In the same way, we have to convert anger into some kind of energy that is more constructive, because anger is you. Without anger you have nothing left. That is the work of meditation.
