Things flourish, then each returns to its root. Returning to the root is called stillness: Stillness is called return to life, return to life is called the constant; knowing the constant is called enlightenment.
Peacefulness is an inner sense of calm - it comes from becoming still - in order to reflect and meditate on our inner wisdom and receive answers. A peaceful heart is one that is free from worry and rouble. It's becoming quiet so we can look at things quietly so we can more clearly understand them and thus come up with creative solutions. It is learning to live in the present. Freedom from desire leads to inner peace.
There was something formless and perfect before the universe was born. It is serene. Empty. Solitary. Unchanging. Infinite. Eternally present. It is the mother of the universe. For lack of a better name, I call it the Tao. It flows through all things, inside and outside, and returns to the origin of all things. The Tao is great. The universe is great. Earth is great. Man is great. These are the four great powers. Man follows the earth. Earth follows the universe. The universe follows the Tao. The Tao follows only itself.
Other people are joyous, like on the feast of the ox, like on the way up to the terrace in the spring. I alone am inert, giving no sign, like a newborn baby who has not learned to smile.
