Uttara-kāṇḍa - Part 2 - Rāvaṇa's Misdeeds
Even after having been cursed by Anaraṇya, Rāvaṇa continued to torment the worlds. Devarṣi Nārada warned him against it, but the rākṣasa paid no heed to the muni’s words. Learning of Rāvaṇa’s intentions to conquer Yama-loka, Nārada rushed to Yama’s abode and alerted him of the danger of the rākṣasa. Even as Nārada was speaking to Yama, Rāvaṇa started attacking the place mounted on his puṣpaka-vimāna. Yama’s men subdued the rākṣasas and grievously wounded them.
