Sometimes something wrong is going on in the world and we think it is the other people who are doing it and we are not doing it.
But you are part of the wrongdoing by the way you live your life. If you are able to understand that, not only you suffer but the other person suffers, that is also an insight.
When you see the other person suffer you will not want to punish or blame but help that person to suffer less. If you are burdened with anger, fear, ignorance and you suffer too much, you cannot help another person. If you suffer less you are lighter more smiling, pleasant to be with, and in a position to help the person.
Activists have to have a spiritual practice in order to help them to suffer less, to nourish the happiness and to handle the suffering so they will be effective in helping the world. With anger and frustration you cannot do much. ~Thich Nhat Hanh
