Which of the following illustrates the concept of satyagraha?
practicing yoga in order to become more peaceful
camping out by a “no loitering” sign to protest the law
refusing to buy goods from certain places because of their laws
boycotting a store that has poor business practices

The correct answer is:

Refusing to buy goods from certain places because of their laws.

Satyagraha is a translation from Sanskrit and Hindi for “holding onto truth”.  This concept was introduced in the early 20th century by Mahatma Gandhi to name a firm nonviolent resistance to evil.

Gandhi’s satyagraha grew a major tool in the Indian fight against British imperialism. His nonviolent noncooperation movement included boycotts not only of British manufacturers but of institutions operated or aided by the British in India: legislatures, courts, offices, schools
