To invoke Ganesha is to remove whatever is blocking your success in life or your goals. Ganesha's vahana is a mouse, which is an extension of him and his power. His vahana goes where Ganesha cannot, so even the smallest of obstacles can be removed.
This amulet can be worn around the neck or placed on a flat surface you look at often. Good for an alter or your dresser, be reminded of Ganesha daily.
