Water is fluid, soft, and yielding. But water will wear away rock, which is rigid and cannot yield. As a rule, whatever is fluid, soft, and yielding will overcome whatever is rigid and hard. This is another paradox: what is soft is strong.
Don't think you can attain total awareness and whole enlightenment without proper discipline and practice. This is egomania. Appropriate rituals channel your emotions and life energy toward the light. Without the discipline to practice them, you will tumble constantly backward into darkness.

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.
