The sphere represents completion, the realization of all possibilities. To carve a sphere one must cut away a mass of rock which can be as much as ten times the finished creation. Thus a sphere symbolizes all that we need to release in order to reach our goals and attain perfection. Many use a sphere while meditating as they believe it helps to release worry and may help to take them to a deeper state. A sphere is also the perfect centerpiece for a crystal arrangement or rock altar. In feng shui, the ancient art of creating optimal energy flow in an environment, a sphere is ideal to place in the center of a room for its balancing abilities.
