"If all trees bore the same kind of fruit, it would cease to be delicious."

"How shall we utilize these gifts and expend these bounties? By directing our efforts toward the unification of the human race. We must use these powers in establishing the oneness of the world of humanity, appreciate these virtues by accomplishing the unity of whites and blacks, devote this divine intelligence to the perfecting of amity and accord among all branches of the human family so that under the protection and providence of God the East and West may hold each other’s hands and become as lovers. Then will mankind be as one nation, one race and kind—as waves of one ocean. Although these waves may differ in form and shape, they are waves of the same sea. Flowers may be variegated in colors, but they are all flowers of one garden. Trees differ though they grow in the same orchard. All are nourished and quickened into life by the bounty of the same rain, all grow and develop by the heat and light of the one sun, all are refreshed and exhilarated by the same breeze that they may bring forth varied fruits. This is according to the creative wisdom. If all trees bore the same kind of fruit, it would cease to be delicious. In their never-ending variety man finds enjoyment instead of monotony."
