If you charge off with some political agenda that is not informed by clarity, you are going to end up with business as usual. The road to hell is paved with good intentions but it is not paved with clarity.
When we bear witness, when we become the situation - homelessness, poverty, illness, violence, death - the right action arises by itself. We don't have to worry about what to do. We don't have to figure out solutions ahead of time. Peacemaking is the functioning of bearing witness. Once we listen with our entire body and mind, loving action arises.
