What is satyagraha?

To achieve success in South Africa, Gandhi's most effective tool is a unique creation of his own. He names it satyagraha which translates to soul force. Satya means truth and graha is defined as firmness or force. Satyagraha is "the vindication of truth not by infliction of suffering on the opponent but on one's self." Again, Gandhi's selfless philosophy is apparent. Satyagraha abandons the eye for an eye attitude in favor of returning good for evil until the evil doer is exhausted.
