The Surúpas, Haris, Satyas, and Śudhís were the classes of gods, each comprising twenty-seven, in the period of Támasa, the fourth Manu. Śivi was the Indra, also designated by his performance of a hundred sacrifices (or named Śatakratu). The seven Rishis were Jyotirdhámá, Prithu, Kávya, Chaitra, Agni, Vanaka, and Pivara. The sons of Támasa were the mighty kings Nara, Khyáti, Śántahaya, Jánujangha, and others.
