I found this on the net and I thought it a useful site for explaining the concepts of non-violent resistance. Gives an overview and Gandhi's position is explained well.

1. Introduction
"People try nonviolence for a week, and when it 'doesn't work' they go back to violence, which hasn't worked for centuries."
-Theodore Roszak
In recent years there has been a dramatic increase in the number of people around the world who have taken part in nonviolent political action. It is clear, however, that there is considerable debate about the precise meaning of nonviolence. For some, nonviolent action is an expedient technique for dealing with conflict or bringing about social change; for others, nonviolence is a moral imperative or even a way of life.

Along with Aldous Huxley, who claimed that "Good ends ... can only be achieved by the employment of appropriate means", and that "The end cannot justify the means, for the simple reason that the means employed determine the nature of the ends produced" (Huxley, 1938, p.9), Gandhi maintained that "The means may be likened to a seed, the end to a tree: and there is just the same inviolable connection between the means and the end as there is between the seed and the tree" (Gandhi, 1961, p. 10). He added that "They say "Means are after all means." I would say, "means are after all everything." As the means so the ends. There is no wall of separation between means and ends" (Young India, 17 July, 1924), and,
"if one takes care of the means, the end will take care of itself" (Harijan, 11 February, 1939).
