They will be celebrated over the Earth as high-souled princes ruling over powerful kingdoms. Born of thee, dissensions will break out among them ending in their destruction at one another's hands excepting yourself. O foremost of regenerate persons, in that age also, endued with austere penances, thou wilt distribute the Vedas into diverse classes. Indeed, in that dark age, thy complexion will become dark. Thou shalt cause diverse kinds of duties to flow and diverse kinds of knowledge also. Although endued with austere penances, yet thou shalt never be able to free thyself from desire and attachment to the world. Thy son, however, will be freed from every attachment like unto the Supreme Soul, through the grace of Madhava. It will not be otherwise. He whom learned Brahmanas call the mind-born son of the Grandsire, viz., Vasishtha endued with great intelligence and like unto an ocean of penances, and whose splendour transcends that of the Sun himself, will be the progenitor of a race in which a great Rishi of the name of Parasara, possessed of mighty energy and prowess, will take his birth. That foremost of persons, that ocean of Vedas, that abode of penances, will become thy sire (when thou wilt take birth in the Kali age). Thou shalt take thy birth as the son of a maiden residing in the house of her sire, through an act of congress with the great Rishi Parasara. Doubts thou wilt have none with respect to the imports of things past, present, and future.
