Feng Shui, which literally means wind and water, sees the world as completely alive with its own chi or personality that is directly affected by such details as the arrangement of furnishings, the location of doors and windows, and the choice of colors and materials. Balancing the chi is the key to good Feng Shui. When in balance, there is a harmonious interaction of yin and yang energies (light/dark, hot/ cold, male/female, etc.), and harmony and good fortune prevail.
