Non-violence is very weak in the theoretical sense; it cannot defend itself. But it is most powerful in the action situation where people are using non-violence because they want desperately to bring about some change. Non-violence in action is a very potent force and it can't be stopped. The people who are struggling have the complete say-so. No man-made law, no human ruler, no army can destroy this. There is no way it can be destroyed... And so, if we have the capacity to endure, if we have the patience, things will change.
