Tree - Ash Represents water, Marriage of opposites, linking inner and outer worlds, mental clarity. Used in healing, protection and sea magic.  Ash is the link between the inner and outer worlds.  We are able to function in deep, watery places, in the realms of the underworld.  It is our flexible, psychic strength.  It is the weave of fate and the guardian of peace.  Take care to see things in their larger context.  Note how all actions have their reactions and note how you affect the world with your actions, physical and spiritual. Take bold action when action is called for.  The challenge of Ash is the determination of hidden influences and appearances.  Things are not always as they seem and you must be perceptive enough to see what is noble. There is a tendency to separate yourself or be cut off from the world.
