The family of humanity
There is only one humanity and we should live together as in a big family. The roots of all humans come from a common heart. If we treat eachother lovingly, there will be no heart problems or disturbances in the circulatory system of humanity.
Every injury to a group of people is ultimately hurting all of us and is defecting our own emotional development. The loving intercourse with eachother - independent of race, religion, culture, and so on - lets the earth newly blossom and makes it into a nurturous land for all humans.
