When we protest against a war, for example, we may assume that we are a peaceful person, a representative of peace, but this might not be true. If we look deeply, we will observe that the roots of war are in the unmindful ways we have been living. This is the way of understanding and love. With this insight, we can see clearly and help our government see clearly. This is far more effective than angrily condemning others.
Anger always accelerates the damage.
All of us, even pacifists, have pain inside. We feel angry and frustrated, and we need to find someone willing to listen to us who is capable of understanding our suffering. In Buddhist iconography, there is a bodhisattva named Avalokitesvara who has one thousand arms and one thousand hands, and has an eye in the palm of each hand. One thousand hands represent action, and the eye in each hand represents understanding. When you understand a situation or a person, any action you do will help and will not cause more suffering.
