According to Mahatma Gandhi, the major means of satyagraha are: Non-cooperation and Civil disobedience. Gandhi believed in using nonviolent resistance and civil disobedience as powerful tools for social and political change. These methods were central to his philosophy of satyagraha, which means truth-force or truthful insistence. While strikes and demonstrations can be part of a broader strategy of nonviolent resistance, they are not the primary means as identified by Gandhi.
