PARÁŚARA.--Lakshmí, the bride of Vishńu, was the daughter of Bhrigu by Khyáti. They had also two sons, Dhátri and Vidhátri, who married the two daughters of the illustrious Meru, Áyati and Niryati; and had by them each a son, named Práńa and Mrikańd́a. The son of the latter was Márkańd́eya, from whom Vedaśiras was born. The son of Práńa was named Dyutimat, and his son was Rájavat; after whom, the race of Bhrigu became infinitely multiplied.
