Lord Ganesha is considered to be the son of Shiva and Parvati. He possesses the head of an elephant on which there’s a tiara. His four hands hold a symbolic object like the Trishul or trident. Other symbolic objects carried by Lord Ganesha are a goad or Ankush and a lotus. Lord Ganesha is known as the deity of wisdom and auspiciousness and he is said to have a great sense of humor as well.
The association between Lord Ganesha and the Chaturthi is due to the fact that he was born on the 4th day of the fortnight of the Hindu lunar month of Magh. Hence, his birth anniversary celebration is known as Ganesh Chaturthi.
An interesting story behind Lord Ganesha’s birth is that his mother Parvati had once created a human figure and instilled life in it, thus asking it to guard the door while she had gone on a bath. During this time, Lord Shiva came to see his wife after a prolonged period of meditation at Mountain Kailash. When stopped by the human figure from entering the house, Lord Shiva was outraged and cut off the former’s head.
Very soon, Shiva came to know that the human figure was created by Parvati. So, he sent his attendants to look for the head of the first living object they could find. The attendants found an elephant and cut off its head to place on the human figure’s body so as to bring him back to life. This is why Lord Ganesha is seen to have an elephant head. He is also known as Ganpati or chief of the “Ganas” or Lord Shiva’s attendants.
