A 'Laddoo' car with an idol of Lord Ganesh is unveiled in Hyderabad on Friday. The car, designed by Sudhakar, is equipped with 120 cc engine and can run with a speed of 50 kmph. Ganesha Chaturthi festival is celebrated on the birthday (rebirth) 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.
