He has four hands, elephant's head and a big belly. His vehicle is a tiny mouse. In his hands he carries a rope (to carry devotees to the truth), an axe (to cut devotees' attachments), and a sweet dessert ball -laddoo- (to reward devotees for spiritual activity). His fourth hand's palm is always extended to bless people.
A unique combination of his elephant-like head and a quick moving tiny mouse vehicle represents tremendous wisdom, intellegence, and presence of mind.
