Sacred depictions of trees have been around for centuries and are prominent in most world religions, including Judaism and Buddhism. This geometric symbol is at the center of the mystical Kabbalah tradition, but it also showed up in Ancient Egypt over 3,000 years ago. While its roots are fairly esoteric, the spatial formation of the symbol should be quite familiar to you. The National Mall in Washington, D.C., for instance, is even constructed in this exact shape. The Tree of Life is said to depict man’s divine unity with the universe and can be understood as a map of the human mind or psyche.
