This document discusses Mahatma Gandhi's concept of satyagraha, or non-violent resistance. It defines satyagraha as a struggle for truth using non-violent means. Gandhi successfully applied satyagraha in Champaran in 1916 to improve the conditions of indentured farmers growing indigo. He defied a government order to leave and eventually pressured authorities to form an inquiry committee. Gandhi's principles for satyagraha included non-violence, truth, not stealing, and chastity. The document also briefly mentions satyagrahas Gandhi led in Ahmedabad and Kheda to increase mill workers' wages and aid peasants during famines.
