Because anger and hostility destroy our peace of mind, it is they that are our real enemy. Anger ruins our health; a compassionate attitude restores it. If it were basic human nature to be angry, there’d be no hope, but since it is our nature to be compassionate, there is.
The source of a happy life is within us. Troublemakers in many parts of the world are often quite well-educated, so it is not just education that we need. What we need is to pay attention to inner values.
Our visit to this planet is short, so we should use our time meaningfully, which we can do by helping others wherever possible. And if we cannot help others, at least we should try not to create pain and suffering for them.
