Symbols are part of the codes that are the building blocks of our universe. To carry any symbol on you is to carry the essence of the energy it possesses. According to the Jewish mysticism, the kabbalic structure of the Tree of life is the symbol of our body, our cosmos, and the hierarchy of forces working within the human reach. It symbolises the ten spheres and within them the ten planets in our cosmos. The tree of life is our DNA code, and evolution. The tree of life symbolises the evolved human being.
