The best antidote against anger is to be prepared, to have worked on the topic before something happens. It is good to be already wearing the parachute before jumping out of the window.
If we are suddenly struck by anger, the best is to imagine the Lama above our head, and then—like a bucket of water being emptied—his blessing flows through us and we become the Lama. That is the fastest method.
In the different phases of meditation, we learn to see how feelings appear, try to catch us, and then dissolve again. When one has seen this often enough during meditation without reacting to it, then one has a protective distance for ordinary life. And that is then a huge advantage.
