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.
LaoziShe who is centered in the Tao can go where she wishes, without danger. She perceives the universal harmony, even amid great pain, because she has found peace in her heart. Music or the smell of good cooking may make people stop and enjoy. But words that point to the Tao seem monotonous and without flavor. When you look for it, there is nothing to see. When you listen for it, there is nothing to hear. When you use it, it is inexhaustible.
Laozi
