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.
People aren't against you; they are for themselves. The most dangerous risk of all - the risk of spending your life not doing what you want on the bet you can buy yourself the freedom to do it later. He who conquers others is strong, he who conquers himself is mighty.
Man at his birth is supple and tender, but in death, he is rigid and hard. Thus, suppleness and tenderness accompany life, but rigidity and hardness accompany death.
