Ilvala


Ilvala and Vatapi were rakshasas and brothers. Legend has it that both were vanquished by the sage Agastya.

Rakshasa

They ruled from Badami, formerly known as Vatapi, named after rakshasa king Vatapi. According to the Mahābhārata, Vatapi ruled the area along with Ilvala.
Once Ilvala hosted a tapasvi Brahmin with reverence and asked him to grant a boon. He desired to have a son equal to Indra. But the sage did not oblige. Following this, his anger turned to hatred against all Brahmins and mendicants. Ilvala and Vatapi took a grudge against all sages.
Vatapi knew the art of transformation and had the power to change into any life form. Ilvala knew the ‘Mritasanjivani’ mantra to bring back the dead. They used these powers to loot and kill. Ilvala invite a brahman to a feast and Vatapi would turn himself into a Goat.

Encounter with Agastya

Ivala invited the sage Agastya and received him with reverence and honour. Sage Agastya, with his divine power, knew the intention of the hosts and wanted to end their transgressions. Agastya ate the food served to him. As soon as the sage finished eating, Ilvala called,"Vatapi atragacha". Immediately, Agastya passed his right hand over his stomach and said,"Vatapi Jeernobhava". Vatapi could not come out of Agastya's stomach and that was the end of the demon. Ilvala, was scared. He went on shouting "Vatapi atragacha" Agastya then said, "Oh, you wicked Ilvala, you wanted to kill me, but your brother Vatapi cannot come out! He is already digested". Ilvala decided to take revenge on Agastya for killing his brother and attacked Agastya. With the power of his tapas, Agastya reduced Ilvala to ashes.
This happened in the southernmost state of Tamil Nadu place where known as Konnur got killed by sage Agastya. And the present day name changed to Villivakkam in chennai. And the burnt place is Kolathur in chennai. Both places has shiva temple installed by Agastya.
