Still water is like a piece of glass. It is at perfect level. The mind and heart of a wise man is at peace. Seek a mind that is still like water. A mind like a rushing river offers no glimpse of the self. However a mind like a tranquil pond offers a clear reflection. You can look into it, and see into your inner nature. It has been said that still waters run deep. To see deep into yourself, you must have a still mind.
