The essence of Gandhi's satyagraha techniques and nonviolent methods is his search for Truth rooted in his confidence in the human conscience. His campaigns could elicit change within people by appealing to their sense of a moral code, because people know they ought to do what is right and avoid evil. In the search for Truth, conscience becomes the standard of moral truth. Gandhi touched the world by appealing to that standard.
Conscience is an abstraction, and individuals put it into practice differently.
This can cause questions about what conscience is. Society tends to think of conscience as that little voice in the back of the mind that speaks when a person is confronted with an ethical situation. The grayness of this principle lies in the individual's life experiences to distinguish right from wrong. It is so subjective because people are reared in different environments and take part in different experiences. Even if experiences were the same for people, their reactions to these events would be unique to their personalities.
