Water is soft, fluid 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. ~Lao TsuI guess sand is the same way, loose and giving way, and yet it is used to polish precious stones and minerals. No more comment. I'm just pondering this whole idea and wanted to share it with you.
