A festival or gala is an event, usually and ordinarily staged by a local community, which centers on and celebrates some unique aspect of that community and the Festival.
Ganesha Chaturthi also known as Vinayaka Chaturthi, is the Hindu festival celebrated on the birthday (re-birth) of Lord Ganesha, the son of Shiva and Parvati.
It is believed that Lord Ganesh bestows his presence on earth for all his devotees during this festival. It is the day Shiva declared his son Ganesha as superior to all the gods, barring Vishnu, Lakshmi, Shiva and Parvati. Ganesha is widely worshipped as the god of wisdom, prosperity and good fortune and traditionally invoked at the beginning of any new venture or at the start of travel.
