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.
The sacrifice which causes sorrow to the doer of the sacrifice is no sacrifice. Real sacrifice lightens the mind of the doer and gives him a sense of peace and joy. The Buddha gave up the pleasures of life because they had become painful to him.
Khadi has been conceived as the foundation and the image of ahimsa. A real khadi-wearer will not utter an untruth. A real khadi-wearer will harbour no violence, no deceit, no impurity.
