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.
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.
The things that have acquired unity are these: Heaven by unity has become clear; Earth by unity has become steady; The Spirit by unity has become spiritual; The Valley by unity has become full; All things by unity have come into existence.
The mature person perceives the fruitlessness of rigid, external methodologies; Remembering this, he keeps his attitude unstructured at all times and thus is always free to pursue the Integral Way. He studies the teachings of the masters. He dissolves all concepts of duality. He pours himself out in service to others.
