When King Indra threw his club at Vrtrasura, Vrtrasura caught it in his left hand and retaliated by using it to strike the head of Indras elephant. Thus Indras attack was a disastrous failure. Indeed, Indras elephant was injured and thrown back fourteen yards. Therefore even though Indra stood with the thunderbolt to hurl against Vrtrasura, he was doubtful, thinking that the thunderbolt might also fail. Vrtrasura, however, being a Vaisnava, assured Indra that the thunderbolt would not fail, for Vrtrasura knew that it had been prepared in accordance with the instructions of Lord Visnu. Although Indra had doubts because he could not understand that Lord Visnus order never fails, Vrtrasura understood Lord Visnus purpose. Vrtrasura was eager to be killed by the thunderbolt manufactured according to Lord Visnus instructions because he was sure that he would thus return home, back to Godhead. He was simply waiting for the opportunity of the thunderbolts being released. In effect, therefore, Vrtrasura told Indra, If you want to kill me, since I am your enemy, take this opportunity. Kill me. You will gain victory, and I shall go back to Godhead. Your deed will be equally beneficial for both of us. Do it immediately.
