There was some defect in Tvaá¹£á¹Ä’s chanting of the mantra because he chanted it long instead of short, and therefore the meaning changed. Tvaá¹£á¹Ä intended to chant the word indra-Å›atro, meaning, “O enemy of Indra.†In this mantra, the word indra is in the possessive case (á¹£aá¹£á¹hÄ«), and the word indra-Å›atro is called a tat-puruá¹£a compound (tatpuruá¹£a-samÄsa). Unfortunately, instead of chanting the mantra short, Tvaá¹£á¹Ä chanted it long, and its meaning changed from “the enemy of Indra†to “Indra, who is an enemy.†Consequently instead of an enemy of Indra’s, there emerged the body of Vá¹›trÄsura, of whom Indra was the enemy.
