Sūta said: In his previous birth Rāvaṇa was Hiraṇyakaśipu. That Rākṣasa ruled as king for thirteen sets of four Yugas. The period (of his rule) reckoned in years in accordance with human calculation comes to fifty-six million one hundred and sixty-thousand years. O Brāhmaṇas, he could give terrible sleepless nights to the Devas and sages. In the twenty-fourth Tretā-yuga, the power of penance of Rāvaṇa was exhausted and dwindled down. Coming into contact with Rāma, the son of Daśaratha, he met with destruction along with his followers.
