The tree of life is a fundamental widespread mytheme or archetype in many of the world's mythologies, religious and philosophical traditions. It is closely related to the concept of the sacred tree. The tree of knowledge, connecting to heaven and the underworld, and the tree of life, connecting all forms of creation, are both forms of the world tree or cosmic tree, and are portrayed in various religions and philosophies as the same tree.
