The Story Behind Onam Festival

There is a very popular story about the Onam festival. This story is considered by the Malayali-speaking people as the basis of this festival.

The Great King Mahabali

According to mythology, there used to be a king in ancient times, King Mahabali, who was the grandson of Prahlad, a beloved devotee of Lord Vishnu. The fame of King Bali was increasing among the people of the earth; due to his good deeds and good behaviour towards his subjects, his fame was on the rise. King Mahabali, despite being a demon king, used to take great care of his subjects, and his subjects respected him a lot. One of the characteristics of the king was that he actively participated in charity. 

Conflict Between Other Gods And King Mahabali

As per the plan,  Lord Vishnu took birth in the form of Vamana (Brahman) in the house of sage Kashyap. The child gradually grew up and became a young man. One day when the king was planning a big Yagya, Lord Vishnu, in the form of a Brahmin, reached the kingdom of Mahabali and met the king. On seeing Lord Vishnu, Shukracharya recognised him and understood his plan.

Lord Vishnu And King Mahabali

As per the tradition, Shukracharya warned King Mahabali; he said to the king, “Rajan, this is Vishnu; surely he has come to ask something from you. Don’t commit to charity without asking me.”

However, King Mahabali ignored this talk of Shukracharya. The king then said to Lord Vishnu, who came in the guise of a Brahmin, you can ask for whatever you want. On this, Lord Vishnu asked the king for three steps of land. The king smiled and said that you could take three steps of land wherever you wanted.

As the king said this, Lord Vishnu assumed his cosmic form and covered the entire earth in one step, the heaven in the second step. Then he asked King Bali where he should put his third leg. On this, the demon king Mahabali smiled and said – “This world is so small for you, what should I do, Lord? Now only my head is left.”

The Devotion Of King Mahabali

As King Mahabali said this, Lord Vishnu at once placLaxmi Yogaed his feet on Mahabali’s head and ordered him to rule in heaven till the end of Kali Yuga. Lord Vishnu was greatly influenced by the devotion and charity of King Mahabali. So he asked Mahabali to ask for a boon before going to Heaven.

Then Mahabali requested Lord Vishnu to allow him to come to earth once a year to meet his subjects. Lord Vishnu accepted his wish. It is believed that Onam is the day when King Mahabali visits the earth to meet his devotees.
