Violence and nonviolence do not depend on an act but on the intention behind it. The basis of violence is anger, lust, hatred, jealousy, greed, frustration and aggression.
A surgeon cuts open a person’s belly; so does a criminal. The action is similar but the surgeon’s intention is to save life and the criminal’s is to destroy it.
Even a war can be nonviolent if it is devoid of anger, hatred, jealousy, or greed and if its intent is to educate those who cannot be educated in any other way. A war can be an act of compassion if it helps to establish the right perspective.
Even charity can be an act of violence if it takes away self-esteem and inflicts slavery.
