According to one interpretation, Ganesha's divine vehicle, the mouse or mooshikam represents wisdom, talent and intelligence. It symbolizes minute investigation of a cryptic subject. A mouse leads a clandestine life below the ground. Thus it is also a symbol of ignorance that is dominant in darkness and fears light and knowledge. As the vehicle of Lord Ganesha, a mouse teaches us to remain always on alert and illuminate our inner-self with the light of knowledge.
