Feng Shui grandmasters highly recommend the Star of David (hexagram) because it connects the seven chakra spheres in your body together so that they can interact with each other to generate energy. Because of its geometric symmetry, Anthropologists claim that the triangle pointing downward represents female sexuality (yang), and the triangle pointing upward, male sexuality (yin); thus, their combination symbolizes unity and harmony. In alchemy, the two triangles symbolize *"fire" and *"water"; together, they represent the reconciliation of opposites. The symbol of intertwined equilateral triangles is thought to bring good luck. It appears occasionally in early Jewish artwork, but never as an exclusively Jewish symbol. The Star of David is an excellent crystal energy balancing tool. When you have the Star of David, it will protect you as it will create an energy shield for you. It will create a harmonious environment or space clearing.
