In Norse mythology, Yggdrasil is the World Tree connecting nine realms. In Kabbalah, the Tree of Life (Etz Chaim) diagrams the structure of creation and the path of divine emanation through ten sephirot. In Buddhism, the Bodhi tree under which Buddha achieved enlightenment represents the possibility of awakening.
The tree serves as apt metaphor for life itself: growing from seed, reaching both down and up, providing shelter and sustenance, changing with seasons yet enduring. Its interconnected branches suggest how all existence connects to common source.
The symbol also represents knowledge and wisdom—eating from the Tree of Knowledge in Genesis, Druids' sacred oak groves, the Buddha's enlightenment under the Bodhi tree. Trees connect earth and sky, material and spiritual, embodying the axis mundi (world axis) that centers reality.
Modern usage of the tree in evolutionary biology, family trees, and organizational charts continues this ancient symbolic tradition of representing hierarchical interconnection.
