After thus rebuking Rāvaṇa, Lord Rāmacandra fixed an arrow to His bow, aimed at Rāvaṇa, and released the arrow, which pierced Rāvaṇa’s heart like a thunderbolt. Upon seeing this, Rāvaṇa’s followers raised a tumultuous sound, crying, “Alas! Alas! What has happened? What has happened?” as Rāvaṇa, vomiting blood from his ten mouths, fell from his airplane, just as a pious man falls to earth from the heavenly planets when the results of his pious activities are exhausted.
