etadācaṣṭa me rājandevarṣirnāradaḥ purā |
vyāsaścaiva mahāyogī saṃjalpeṣu pade pade || 40 ||

Through my grace, O great Rishi thou shalt behold in this world a shadowy form resembling thy son, moving by the side and never deserting thee for a single moment!--Thus favoured by the illustrious Rudra himself, O Bharata, the Rishi beheld a shadow of his son by his side. He returned from that place, filled with joy at this. I have now told thee, O chief of Bharata's race, everything regarding the birth and life of Suka about which thou hadst asked me. The celestial Rishi Narada and the great Yogin Vyasa had repeatedly told all this to me in days of yore when the subject was suggested to him in course of conversation. That person devoted to tranquillity hears this sacred history directly connected with the topic of Emancipation is certain to attain to the highest end."
