A violent act can never put down another violent act. If you do not believe in violence, you should not exhibit violence in any way. Every act of yours must be based on non-violence. That means you have to build up that capacity within yourself, that faith in the virtue of non-violence. Until that capacity is developed, peace marches, demonstrations, protests and things like that will not bring any real benefit. It would be better for you to sit still and find peace within yourself; then you will be able to take peaceful thoughts, peaceful vibrations, with you wherever you go.
-Sri Swami Satchidananda
