Violence is not really in the act. What’s perceived as violence is the compulsive playing out of that which is in the heart of humanity.
The temptation is to condemn the act, and thus create more violence. Breathing and noticing this allows you to get in touch with how it feels when your body/mind is being used as an instrument for expanding the energy of violence.
May peace prevail in you and through you, into the life of your world. Aloha!
