अवध्यं दैवतैर्विष्णो समरे जहि रावणम्॥

Born to these three queens, in the form of a human, O Lord Viṣṇu, may Your Lordship kill Rāvaṇa in war. He has become very strong because of the benediction he has received from Lord Brahmā and his personal strength. He has become a thorn to the worlds and cannot be killed by the celestials.1
