The legend behind the celebration is that Mahabali Chakravarthi who was ruling the earth was driven out of the earth by Mahavishnu in the incarnation of Vamana. Since Mahabali was a staunch devotee of Mahavishnu, he was granted a boon by the lord that Mahabali can visit earth every year to see the places he ruled earlier. It is believed that Mahabali comes during this period every year. The celebration is supposed to welcome him and show him that though the conditions are not as good as during his rule, but still is in a pretty good condition.
