Feng shui, meaning wind and water, is the ancient art of placement and the balancing of energies. When applied to arranging one’s home, the idea is to allow the energy to flow through the space in a positive way to improve the resident’s life. This is done by positioning the furniture in a flowing, navigable layout, using mirrors to reflect certain energies and bringing in natural elements like plants or water to balance out the chi.
