Read the passage from Sugar Changed the World.

Then Gandhi invited each person in the theater to join him in an exceptional oath, a pledge not to register, not to accept the government's rules, even if that resulted in severe punishment. Gandhi insisted that every person weigh the commitment and make a personal choice. "Every individual," he explained, must make the oath him- or herself,

facing not to his neighbor, but his God. Nor should it be taken in order to gain power over anybody but oneself, for the power of an oath is defined by what one man can promise to do, and what he is willing to suffer: insult, incarceration, hard labor, flogging, fine, deportation, and even death.

Everyone in the audience raised his or her hand.

Gandhi bound the crowd together to follow a new path, which he called Satyagraha—which means "truth with force," or "firmness." It is also called "love-force." While the goal of violence is to defeat and vanquish the enemy, the goal of Satyagraha is to convince or convert the opponent. "He must be weaned from error by patience and sympathy." A person who believes in Satyagraha will not fight physically, but instead resists through his or her own inner courage, knowing he might be jailed or beaten.
