śanaiścaraḥ sūryaputro bhaviṣyati manurmahān |
tasminmanvantare caiva saptarṣigaṇapūrvakaḥ |
tvameva bhavitā vatsa matprasādānna saṃśayaḥ || 52 ||

Endued with penances and instructed by me, thou wilt behold the incidents of thousands and thousands of ages long past away. Thou wilt see through thousands and thousands of ages also in the future. Thou shalt, in that birth, behold me, O ascetic,--me that am without birth and death,--incarnated on Earth (as Krishna of Yadu's race), armed with the discus. All this will happen to thee, O ascetic, through the merit that will be thine in consequence of thy ceaseless devotion to me. These words of mine will never be otherwise. Thou shalt be one of the foremost of creatures. Great shall be thy fame. Surya's son Sani (Saturn) will, in a future Kalpa, take birth as the great Manu of that period. During that Manwantara, O son, thou shalt, in respect of merits, be superior to even the Manus of the several periods. Without doubt, thou shalt be so through my grace. Whatever exists in the world represents the result of my exertion. The thoughts of others may not correspond with their acts. As regards myself, however, I always ordain what I think, without the least impediment! Having said these words unto the Rishi Apantaratamas, otherwise called by the name of Saraswat, the Supreme Lord dismissed him, saying unto him.--Go. I am he that was born as Apantaratamas through the command of Hari. Once more have I taken birth as the celebrated Krishna-Dwaipayana, a delighter of the race of Vasishtha.
