Satyagraha is Gandhi's gift to the world. When used against oppressive, colonial, and violent governments, the use of non-violence, passive and active resistance, and a willingness to suffer through the oppressor's attacks, has proven effective for equality and freedom movements throughout the world. Satyagraha relies on the purification of the oppressor through the oppressor; through suffering endured without hatred. It has been successfully employed in Jim Crow America, Nazi Germany, and apartheid South Africa. Its efficacy is real and clear.
