PRITHU had two valiant sons, Antarddhi and Pálí. The son of Antarddhána, by his wife Sikhańd́ińí, was Havirdhána, to whom Dhishańá, a princess of the race of Agni, bore six sons, Práchínaverhis, Śukra, Gaya, Krishńa, Vraja, and Ajina. The first of these was a mighty prince and patriarch, by whom mankind was multiplied after the death of Havirdhána. He was called Práchínaverhis from his placing upon the earth the sacred grass, pointing to the east. At the termination of a rigid penance the married Savarńá, the daughter of the ocean, who had been previously betrothed to him, and who had by the king ten sons, who were all styled Prachetasas, and were skilled in military science: they all observed the same duties, practised religious austerities, and remained immersed in the bed of the sea for ten thousand years.
