The document discusses non-violence (ahimsa) and social harmony. It notes that October 2nd is celebrated as International Non-Violence Day to commemorate Mahatma Gandhi's birthday and spread the message of ahimsa. Ahimsa is essential to human civilization and social progress, as violence harms people physically, mentally, socially, politically and ideologically. Non-violent resistance, tolerance and goodwill are needed to achieve social justice. While ahimsa was Gandhi's guiding principle, today many including leaders in Guinea, Kenya and Nepal are promoting non-violence and harmony through education and community awareness to ensure a sustainable future for humanity.
