Saint Agastya’s character in the Hindu mythology has its own significance. Many notable incidents have direct or indirect links to him and his actions. One out of those is the one involving the two demon brothers, Batapi and Illwala.
Both Batapi and Illwala had the weird ability to change their appearances as and when they want. Demons as they were, they used that rare ability for their foolish and evil fun. For some reason, they developed a strong hatred for the Brahmins. So, they devised a plan to kill all the brahmins around. They would invite the Brahmins to their home to offer them food, feigning their benevolence. When the brahmins accepted their invitation, Batapi would turn into a goat, and Illwala would kill that goat to prepare tasty non-vegetarian dishes and feed the Brahmins. After a while, Illwala would shout: “Batapi, come out.” Batapi would come alive, tear open the stomach of the Brahmin, in the process leaving him dead.
When such instances continued to multiply, Saint Agastya came to know of this. To teach the demon duo a lesson, he wished to be their guest. The demon brothers got elated to have the saint as their prey. They treated the guest in their planned manner and offered the same non-vegetarian dish. Saint Agastya relished the food and belched in satisfaction, thus killing Batapi inside his stomach using his saintly abilities. When Illwala yelled, “Batapi, come out!”, Baatapi did not turn up. Smelling something wrong, he went on to attack Saint Agastya. Saint Agastya chanted some mantras and turned Illwala into a handful of ash, thus relieving the brahmins of the torture of the demon brothers.
If the Almighty has blessed you with some rare abilities, use them benevolently, thus contributing towards the larger good of the society you are a part of. Else, the Almighty can devise his own way to wipe out your very existence.
