In winter the trees are stripped of leaves, animals hibernate, and people stay inside more. There is still life but it is found in the interior. If we consider the power of a seed with all of its energy and entire blueprint for life inside waiting patiently to be born, we may begin to understand the power of the Water Element. The Bladder and Kidney are uniquely tied to the Water Element.  Similar to a seed in many ways, the Kidney holds the DNA and our blueprint for life.  The Kidney gives us the gifts of ambition, will, and drive.  It is how we connect to our ancestors and to the unique thread that binds all things in the universe.  Just as a reservoir on earth holds the water reserves for the planet, the Bladder holds the reserves for the body and controls when and how we use them.
