The Tree of life is illustrated in this piece as a ceremonial decorated tree used by many First Nations tribes.    This tree represents the generations of life, the present (Trunk), our ancestors (the roots), the children (branches) and the future generations (buds, leaves).  The colored ribbons or prayer flags, symbolize the directions and the colored roots are the four nations. Bells are used to annunciate the four divine powers. The Creator’s Thunderbird is a messenger from one power to another.  The beating of his wings creates the winds and he is associated with the elements; rain, thunder and lighting. The eagle too is a messenger from creator to mankind, although he is mistaken for the thunderbird by some, they are separate powers.
