The Soul as Water.

I read this somewhere, and it made me curious. What is water, and how is it like a soul? First, I have trouble differeniating among mind, heart, and soul, so perhaps any of these terms would fit. Don't expect this to be a perfect metaphor.

• Water moves to freer spaces. The soul shuns confinement an can rush to the wild--for good or ill.
• Water is essential to life. We need our souls also. They make up the majority of what we really are, even deeper than what we may think or feel. And we need soul from others--most often in some form of art (music, literature, theatre, and such) and some extraordinary relationships. We need to share ourselves that way too. Expression. 
• Water makes an impression on land, rocks, glass--but over time. We need persistence and patience. The soul is powerful but can be destructive if we expect it to act too quickly. Some pieces of glass in my life are still sharp-edged. Others are cloudy and soft, ready to go in a jar or a painted dish.

That's my attempt. Can you think of more ways a soul is like water?
