Mandala comes from a Sanskrit word meaning "circle" or "completion" and represents the Cosmos. Mandalas are used as spiritual teaching tools, to establish a sacred space, and as an aid to meditation. Plus they can attract positive energy to make your life better.
Energy or "qi" (pronounced "chi") is all around us and can be harnessed to improve the quality of our everyday lives. Feng Shui Mandalas help harness that energy to make things better.
In feng shui, the home is divided into 9 zones called the bagua. Each section influences a different aspect of our lives. So you want to make sure the energy is positive and powerful to help you achieve your aims in life. For example, if you wanted to attract new love into your life, you would enhance the back, right section of you house or room which effects relationships and love. You attract good energy, first by clearing a space and removing negative influences, and then by intentionally placing items in the space that you want to achieve.
