Spiritual significance of Onam
According to mythology, King Mahabali was the greatest king of Kerala and it was during his reign that the local people saw the best of times; prosperity and grandeur ruled everywhere.
To end Mahabali’s rule on earth, Lord Vishnu emerged as a Vaman (short Brahmin) and tricked the King to give him whatever land he had. Thereby, King Mahabali was sent to a lower world; but Vishnu also granted him a boon that he could visit his land once every year. Onam celebrates this home-coming of the King.
