A Simple Guide to Empty Your Mind
Also from http://zenhabits.net/mind-like-water/--
"It reminds me of a quote from Bruce Lee:Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water my friend.
I think the appeal is the calmness and peace that you are trying to achieve. Have everything in its place, and empty your mind of busy-ness and junk. Then you are ready for anything that comes your way."
