The tree of life is a mystical and magical tree that is well known in many cultures. It represents our connection to all things -- earth, air, water, fire. In Celtic culture, trees were the centre of all that occurred -- the absence of trees would be the absence of life. In Christian tradition, eating from the tree of life is said to grant immortality. In Norse mythology, the tree of life, or Yggdrasil, binds together all realms of existence. This ancient tree represents our connection to our ancestors and also of our individuality. The stages of a tree's growth through the year mirrors that of the cycle of life, similar to the eternal life/re-birth traditions in many religions.
