Develop universal love. If you cultivate love for all those close to you, you can have unselfish love for humanity. Love for humanity begins at home.
First you love your parents, your brothers, sisters and relatives. Then you love your neighbours, your community and your country. Finally, you love the whole world. Thus, the small seed of love sown in the young mind of the child gradually develops and grows into pure universal love. Love is harmony. It prolongs life.
