Lord Ganesha is depicted with an Ankush, or goad, in one of his hands. Sometimes people confuse it to be an axe. Traditionally goad is used to control elephants in India. Symbolically, Ankush is used by Lord Ganesh to drive mankind forward on the path of self realization.
Ankush symbolizes the need for the control of the elephant size desires which runs amok and ruins the life of a human being. When desires are not controlled it is like an elephant running amok – destroying everything on the path to fulfill the desire.
