How Ganesha born?
Traditional stories tell that Lord Ganesha was created by goddess Parvati, consort of Lord Shiva. Parvati created Ganesha out of sandalwood paste that she used for her bath and breathed life into the figure. She then set him to stand guard at her door while she bathed. However, while she bathed, Lord Shiva returned and as Ganesha didn't know him, he didn't allow him to enter. Lord Shiva became enraged and severed the head of the child and entered his house. After realizing that he had beheaded his own son, Lord Shiva fixed the head of an elephant (in some versions, Airavata, the vehicle of the god Indra) in place of Ganesha's head. In this way, Lord Ganesha came to be depicted as the elephant-headed God.
Why we celebrate Vinayaka Chaturthi ?
The name Ganesha is a Sanskrit compound, joining the words gana , meaning a group, multitude, or categorical system and isha , meaning lord or master. The word gana when associated with Ganesha is often taken to refer to the ganas, a troop of semi-divine beings that form part of the retinue of Shiva The term more generally means a category, class, community, association, or corporation. Some commentators interpret the name "Lord of the Ganas" to mean "Lord of created categories," such as the elements, etc. The translation "Lord of Hosts" may convey a familiar sense to Western readers. Ganapati is a synonym for Ganesha, being a compound composed of ga?a, meaning "group", and pati, meaning "ruler" or "lord".
