In Jewish and Christian mythology we know that the Tree of Life was a gift from God. Planted at the center of paradise (The Garden of Eden) it was the crowing glory. God had given this tree to Adam and Eve as a source of blessing and eternal life. In the winter when the tree loses its leaves this symbolizes death. When the tree sprouts new leaves (new growth) in the Spring this symbolizes resurrection. The tree also bears fruits or seeds, which contain the essence of the tree. This continuous regeneration is a potent symbol of immortality. It is the fruit of the tree that confers immortality in the Jewish creation story.
The Mayan believed heaven is a wonderful and magical place on Earth hidden by a mystical mountain called Tamoanchan. The Mayan tree of life is a cross with its center being the point of absolute beginning. The source of all creation. Its branches passing through each of the three layers of existence. The three layers being the underworld, the earth, and the sky.
The Tree of Life is really an amazing symbol recognized around the world.
