Genesha has become one of the commonest mnemonics for anything associated with Hinduism. This not only suggests the importance of Ganesha, but also shows how popular and pervasive this deity is in the minds of the masses.
The son of Shiva and Parvati, Genesha has an elephantine countenance with a curved trunk and big ears, and a huge pot-bellied body of a human being. He is the Lord of success and destroyer of evils and obstacles. He is also worshipped as the god of education, knowledge, wisdom and wealth. In fact, Genesha is one of the five prime Hindu deities (Brahma, Vishnu, Shiva and Durga being the other four) whose idolatry is glorified as the panchayatana puja.

Significance of the Genesha Form
Ganesha's head symbolizes the Atman or the soul, which is the ultimate supreme reality of human existence, and his human body signifies Maya or the earthly existence of human beings. The elephant head denotes wisdom and its trunk represents Om, the sound symbol of cosmic reality. In his upper right hand Genesha holds a goad, which helps him propel mankind forward on the eternal path and remove obstacles from the way. The noose in Ganesha's left hand is a gentle implement to capture all difficulties.

The broken tusk that Genesha 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.

How Genesha Got His Head
The story of the birth of this zoomorphic deity, as depicted in the Shiva Purana, goes like this: Once goddess Parvati, while bathing, created a boy out of the dirt of her body and assigned him the task of guarding the entrance to her bathroom. When Shiva, her husband returned, he was surprised to find a stranger denying him access, and struck off the boy's head in rage. Parvati broke down in utter grief and to soothe her, Shiva sent out his squad (gana) to fetch the head of any sleeping being who was facing the north. The company found a sleeping elephant and brought back its severed head, which was then attached to the body of the boy. Shiva restored its life and made him the leader (pati) of his troops.
Hence his name 'Ganapati'. Shiva also bestowed a boon that people would worship him and invoke his name before undertaking any venture.
