Mohandas Gandhi spread the concept of nonviolence or ahimsa through his movements and writings. Nonviolence is the practice of avoiding harm to oneself and others, and refers to abstaining from violence based on moral or spiritual principles. Gandhi viewed nonviolence as truth and as the law of one's being. There are various types of nonviolence approaches, and Gandhi advocated for Satyagraha, which aims to attain truth through love and right action by eliminating violence from oneself and society. Nonviolence is significant because it provides tools for opposing wars, violence, and oppression through peaceful means.
