If we are forced, at every hour, to watch or listen to horrible events, this constant stream of ghastly impressions will deprive even the most delicate among us of all respect for humanity.
We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy.
Whether we consider the individual, family, local, national or international level, peace must arise from inner peace. For example, making prayers for peace while continuing to harbor anger is futile. Training the mind and overcoming your anger is much more effective than mere prayer. Anger, hatred and jealousy never solve problems, only affection, concern and respect can do that.
