1. Tree of life (Kabbalah)See also Tree of life (disambiguation) for other meanings of the term. The Tree of Life, or Etz haChayim (עץ החיים) in Hebrew, is a mystical symbol used in the Kabbalah of esoteric Judaism to describe the path to God (usually referred to as HaShem, or "The Name", in kabbalistic texts) and the manner in which he created the world ex nihilo. Kabbalists developed this concept into a full model of reality, using the tree to depict a map of Creation.
