The Tree of Life is common to many cultures. It’s often regarded as all-nourishing and all-giving. Britain was once covered by a mighty oak forest and the tree reverence is a major feature within the Celtic culture. The tree reflects a link between heaven and earth. Roots reach down to the earth and its branches reach up to the heavens. The interlacing branches symbolize the continuity of life. The tree was regarded by the Celts as a source of food, protection form the elements, provider of material shelter, and a source of warmth when making fire with its wood.
