The Tao gives birth to One. One gives birth to yin and yang. Yin and yang give birth to all things... The complete whole is the complete whole. So also is any part the complete whole... But forget about understanding and harmonizing and making all things one. The universe is already a harmonious oneness; just realize it.
Without stirring abroad, One can know the whole world; Without looking out of the window One can see the way of heaven. The further one goes The less one knows.
The Tao is the center of the universe, the good man's treasure, the bad man's refuge. Honors can be bought with fine words, respect can be won with good deeds; but the Tao is beyond all value, and no one can achieve it. Thus, when a new leader is chosen, don't offer to help him with your wealth or your expertise. Offer instead to teach him about the Tao. Why did the ancient Masters esteem the Tao? Because, being one with the Tao, when you seek, you find; and when you make a mistake, you are forgiven. That is why everybody loves it.
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.
