Ganesha, the Hindu God of Success.
Ganesha, the elephant-headed Hindu god who rides a mouse, is one of the faith's most important deities. One of the five primary Hindu deities, Ganesha is worshiped by all sects and his image is pervasive in Indian art.

The son of the Trinity Lord Shiva and Parvati, Ganesha has an elephantine countenance with a curved trunk and big ears atop the pot-bellied body of a four-armed man. He is the lord of success and the destroyer of evils and obstacles, worshiped as the god of education, wisdom, and wealth. Worshippers also regard him as the destroyer of vanity, selfishness, and pride, the personification of the material universe in all its manifestations.

Ganesha's Symbolism
Ganesha's head symbolizes the Atman or the Soul, which is the supreme reality of human existence, while his body signifies Maya or mankind's earthly existence. The elephantine head denotes wisdom and its trunk represents Om, the sound symbol of cosmic reality.
The laddoo or Sweet he holds in his trunk represents the sweetness of the Atman. His fan-like ears convey that he will always hear the prayers of the faithful. And he is humble enough to ride the lowest of creatures, a mouse.
Enjoy!
