If one does not practice non-violence in one's personal relations with others, and hopes to use it in bigger affairs, one is vastly mistaken. Non-violence like charity must begin at home.
But if it is necessary for the individual to be trained in non-violence, it is even more necessary for the nation to be trained likewise. One cannot be non-violent in one's own circle and violent outside it. Or else, one is not truly non-violent even in one's own circle; often the non-violence is only in appearance. It is only when you meet with resistance, as for instance, when a thief or a murderer appears, that your non-violence is put on its trail. You either try or should try to oppose the thief with his own weapons, or you try to disarm him by love. Living among decent people, your conduct may not be described as a non-violent.
Mutual forbearance is non-violence. Immediately, therefore, you get the conviction that non-violence is the law of life, you have to practice it towards those who act violently towards you, and the law must apply to nations as individuals. Training no doubt is necessary. And beginnings are always small. But if the conviction is there, the rest will follow. (H, 28-1-1939, pp441-2)
Universality of Non-violence
Non-violence to be a creed has to be all-pervasive. I cannot be non-violent about one activity of mine and violent about others. (H, 12-10-1935, p376)
It is a blasphemy to say that non-violence can only be practiced by individuals and never by nations which are composed of individuals. (H, 12-11-1938, p328)
In my opinion, non-violence is not passivity in any shape or form. Non-violence, as I understand it, is the most active force in the world...Non-violence is the supreme law. During my half a century of experience, I have not yet come across a situation when I had to say that I was helpless, that I had no remedy in terms of non-violence. (H, 24-12-1938, p393)
Cultivation of Non-violence
I am an irrepressible optimist. My optimism rests on my belief in the infinite possibilities of the individual to develop non-violence. The more you develop it in your own being, the more infectious it becomes till it over-whelms your surroundings and by and by might over sweep the world. (H, 28-1-1939, p443)
I have known from early youth that non-violence is not a cloistered virtue to be practiced by the individual for his peace and final salvation, but it is a rule of conduct for society if it is to live consistently with human dignity and make progress towards the attainment of peace for which it has been yearning for ages past. (GCG, pp42-44, pp170-1)
To practice non-violence in mundane matters is to know its true value. It is to bring heaven upon earth. There is no such thing as the other world. All works are one. There is no 'here' and no 'there'. As Jeans has demonstrated, the whole universe including the most distant stars, invisible even through the most powerful telescope in the world, is compressed in an atom.
I hold it, therefore, to be wrong to limit the use of non-violence to cave-dwellers and for acquiring merit for a favoured position in the other world. All virtue ceases to have use if it serves no purpose in every walk of life. (H, 26-7-1942, p248)
Use on Mass Scale
Unfortunately for us, we are strangers to the non-violence of the brave on a mass scale. Some even doubt the possibility of the exercise of non-violence by groups, much less by masses of people. They restrict its exercise to exceptional individuals. Only, mankind can have no use of it if it is always reserved only for individuals. (H, 8-9-1946, p296)
Efficacy
I have been practicing with scientific precision non-violence and its possibilities for an unbroken period of over fifty years. I have applied it in every walk of life, domestic, institutional, economic and political. I know of no single case in which it has failed. Where it has seemed sometimes to have failed, I have ascribed it to my imperfections. I claim no perfection for myself. But I do claim to be a passionate seeker after Truth, which is but another name for God. In the course of that search, the discovery of non-violence came to me. Its spread is my life mission. I have no interest in living except for the prosecution of that mission. (H, 6-7-1940, pp185-6)
There is no hope for the aching world except through the narrow and straight path of non-violence. Millions like me may fail to prove the truth in their own lives, that would be their failure, never of the eternal law. (H, 29-6-1947, p209)
