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...

Why not simply honor your parents, love your children, help your brothers and sisters, be faithful to your friends, care for your mate with devotion, complete your work cooperatively and joyfully, assume responsibility for problems, practice virtue without first demanding it of others, understand the highest truths yet retain an ordinary manner? That would be true clarity, true simplicity, true mastery.
