The more than 1000 year old tradition of offering Onavillu (a wooden bow with drawings of Deities etched on it) to the Shri Padmanabhswami temple in Kerala
In Malyalam the word Onavillu is created from two words Onam and Villa. Vaman Jayanti is celebrated on the twelfth day in the bright fortnight of Bhadrapad, that is Vaman Dwadashi.
