The broken tusk that Ganesha holds like a pen in his lower right hand is a symbol of sacrifice, which he broke for writing the Mahabharata. The rosary in his other hand suggests that the pursuit of knowledge should be continuous. The laddoo (sweet) he holds in his trunk indicates that one must discover the sweetness of the Atman. His fan-like ears convey that he is all ears to our petition. The snake that runs round his waist represents energy in all forms. And he is humble enough to ride the lowest of creatures, a mouse.
