The sculpture of Ganesh can be used for good feng shui. Feng shui is the art of creating harmonious, healthy, and prosperous environments and is open to using any symbols, images, and ideas that work for the homeowner.
If you look at feng shui from the strict classical perspective or from a scholarly point of view, then Ganesh is really not a classical or typical feng shui cure at all. All classical feng shui cures are based on Chinese history and mythology, and Ganesh belongs to the pantheon of Indian gods. So logically, vastu shastra will have more to say about the energy of Ganesh in your home.
Good feng shui means good energy, and in its essence, the energy cannot be bound to any cultural traditions or symbols. If the energy of Ganesh speaks to your friend, meaning she feels connected to it in some way and receives a certain quality of energy from it—be it protection, blessings or good fortune—then chances are Ganesh is an excellent feng shui cure for her home.
Be sure you know what the energy of Ganesh stands for, what are its mythological and historical associations. You have to have a certain connection to an image or a symbol you bring into your home in order for this symbol to work as a powerful feng shui cure, and Ganesh is no exception.
Ganesh is sure the deity that is very easy to identify. While it may take a bit of research to know which Buddha you have in your home as well as the meaning of specific Buddha mudras, it is much easier with Ganesh. The obvious recognition factor is visual—Ganesh is the deity with the elephant head. Let's see why is it so, as well as why Ganesh is known as the “Remover of Obstacles.”
There are several versions as to why Ganesh has an elephant head, the most popular one being the story where he was beheaded and then his head replaced with an elephant head by his father, Lord Shiva. The symbolism of elephant energy can be interesting to explore here because elephants are a popular feng shui cure. Ganesh is also often depicted with a protruding belly (just like the Laughing Buddha), as well as many arms (anywhere in between four and sixteen).
In time, the main energy that came to be associated with Ganesh is his ability to remove obstacles. Ganesh is often placed in areas that need an opening or clearing; he is also worshipped and brought offerings to when one is starting a business (for example) or embarks on a long and difficult journey.
Even though there are certainly many subtle meanings attributed to Ganesh, especially by longtime worshippers, the one that is most interesting is his connection/association with the base chakra (Muladhara) from which the spiritual awakening energy (Kundalini) originates. True devotees are praying to Ganesh to remove the obstacles to their spiritual growth so that they may achieve and know the Ultimate Truth.
Place Ganesh in any area of your bagua that needs some help or just place the statue (or the image) on your altar. As with the feng shui placement of any deities, do not place Ganesh on the floor or in low energy areas, such as the bathroom, garage or laundry.
