Difference means. Country/rap music. Celtic/Asian dance. Classical/modern art. Etc. Race/Nationality.
If we each celebrate the differences within our own humanity. Then our race/species of human beings can become reunited once again with one another. A unified human species/race means that all that we collectively decide to do will become possible/manifest into our reality.
We are all one humanity, one species and one family. When all of the common peoples unite together to love one another, to live in peace with each other and to exist in harmony. Then we all can find a very rich life we all can live with great meaning.
