In the application of Satyagraha, I discovered, in the earliest stages, that pursuit of Truth did not admit of violence being inflicted on one's opponent, but that he must be weaned from error by patience and sympathy. For, what appears to be truth to the one may appear to be error to the other. And patience means self-suffering. So the doctrine came to mean vindication of Truth, not by infliction of suffering on the opponent but one's own self.
