"Heaven and earth and I coexist, and all things are one with me" ("Zhuangzi") Although the forms of heaven and earth and all things are different, they are the same in origin.

"Nothing , named Heaven and Earth; Being, the mother of all things; Ever-present, wanting to see its wonders; Both have the same origin, but have different names, and are both mysterious and mysterious, the door to all wonders.

" --- Chapter 1 of "Tao Te Ching"
