The tree of life is a fundamental archetype in many of the world's mythological, religious, and philosophical traditions. It is closely related to the concept of the sacred tree. The concept of the tree of life may have originated in Central Asia, and was absorbed by other cultures, such as Scandinavian mythology and Altai shamanism. 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.
