We know of humans and your actions throughout the world - all this is held in water. Energy - thoughts, feelings, actions- moves across the earth and is absorbed by land, condensed in water. This is how we know what is happening in the world. You cannot lie to earth or water... Everything comes through.
If you learn to sink and listen, to feel and open, you will know this, too. We are at peace with ourselves and do not often interact with others. We speak to quiet souls who are happy being alone even when around others. That is a hippos knowledge, a special kind of tone.
