Mental violence has no potency and injures only the person whose thoughts are violent. It is otherwise with mental non-violence. It has potency which the world does not yet know.
Old as I am in age, I have no feeling that I have ceased to grow inwardly or that my growth will stop at the dissolution of the flesh. What I am concerned with is my readiness to obey the call of Truth, my God, from moment to moment, no matter how inconsistent it may appear. My commitment is to Truth, not to consistency.
I do believe that where there is a choice between cowardice and non-violence I would advise violence. Thus when my eldest son asked me what he should have done, had he been present when I was almost fatally assaulted in 1908, whether he should have run away and seen me killed or whether he should have used his physical force which he could and wanted to use, and defended me, I told him that it was his duty to defend me even by using violence.
