Active nonviolence is necessary for those who will offer civil disobedience but the will and proper training are enough for the people to co-operate with those who are chosen for civil disobedience.
I think that training is important. I think you need to learn as much as you can learn. I would say that it's important and probably crucial, but I wouldn't say that everyone has to have it.
Training- training is everything; training is all there is to a person. We speak of nature; it is folly; there is no such thing as nature; what we call by that misleading name is merely heredity and training. We have no thoughts of our own, no opinions of our own; they are transmitted to us, trained into us.
