The existence of land and water, the land for the water and the water for the land, the attraction between the heavens and the earth - all demonstrate a universal harmony. The attraction of the sun and moon to each other, the cosmic order of the stars and the planets, all connected and related with each other, moving and working under a certain law; the regular rotation of the seasons; the night following the day, and the day in its turn giving place to the night; the dependence of one being on another; the distinctiveness, attraction and assimilation of the five elements - all prove the universal harmony.
