The vertical trunk of the Tree of Life represents a connection between the human world and the divine world. The horizontal branches on the tree represent the source and origin of life on earth. Thus, the tree as a whole can be interpreted to represent the interconnected nature of life.
The Tree of Life is a common symbol in many of the world's religions, and it is present in spiritual teachings throughout Asia, North America and Australia. The tree often serves as a symbolic center of the universe, either the source of life on earth or a way of transferring divine knowledge to humans.
